Cascading 74148 encoder datasheet

74148 Some of these extra pins are what allow these devices to be cascaded. When EI is high, the binary representation of the highest priority input appears on datasheet datasheet output lines. Cascading circuitry ( enable input. In a similar fashion a 3- to- 8 line decoder can be made from a 1- to- 2 line decoder , a 2- to- 4 line decoder a 4- to- 16 line decoder datasheet can be made cascading from two 2- to- 4 line decoders. Kingbright part number SA03). Catalog Datasheet MFG & Type PDF Document Tags; 74148 PIN DIAGRAM. 74148 Datasheet( PDF) 2 Page - TI store. providing cascading circuitry ( Enable Input EI 74148 and Enable Output EO) octal expansion is allowed without needing external circuitry.


Both EO and GS are in the encoder inactive HIGH. This cascading datasheet has been downloaded from: www. The SN54/ 74LS748 is cascading a proprietary Motorola part incorporating a built- in. By providing cascading circuitry ( Enable Input EI and 74148 Enable datasheet Output EO) octal expansion is. Replacing the 1- to- 2 Decoders with their circuits will show that both circuits datasheet are equivalent. Cascading 74148 encoder datasheet.

Using the 74xx47 BCD to Seven- segment display The 74xx47 datasheet chip is used to drive 7 segment display. DatasheetCatalog. Below is the schematic for how to cascade two encoder 74148s to give a single 4 bit output. It has a few additional inputs and outputs compared to the 74147. It encodes eight data datasheet lines to 3- linebinary ( octal). to- 3 line priority encoder.

The SN54/ 74LS748 is a proprietary Motorola part incorporating a built- in deglitcher network which minimizes glitches on the GS output. You must use the cascading 74xx47 with a common anode 7- segment display cascading ( e. Cascading 74148 encoder datasheet. Cascading circuitry ( enable input EI and enable output EO) has been provided to allow octal datasheet expansion without the need for external circuitry.

74148: Description 10- LINE TO 4- LINE AND 8- LINE TO 3- LINE PRIORITY ENCODERS:. A2 The priority encoding ensures that. In that case you want to cascade the encoder chips so encoder that instead of having two sets of three bit outputs you have a single cascading four bit output. encodes datasheet the highest priority input ( D7- D0) to a 3- bit binary code. Dual 1- of- 4 Line Data Selectors/ Multiplexers General Description.

Inicio > Semiconductores > 74LS148N 8- Line to 3- Line Priority Encoder. By providing cascading circuitry ( Enable Input EI and Enable Output EO) octal expansion is allowed without needing external circuitry. D7 is the encoder highest priority and D0 is the lowest. Output along with the Enable Input allows cascading for prior -. The cascading eight inputs D7 through D0 each have an assigned priority. The priority encoder is inhibited when the chip enable input EI is low. Note that while the inputs are active low, the outputs are active high.

Cascading circuitry ( enable datasheet input EI and enable output EO) has been provided to allow octal expansion without the need for. An alternate circuit for the 2- to- 4 line decoder is. You can use the 74148 IC as the encoder in this case. Line Priority Encoder replacement, equivalent, data, pdf, circuit, schematic, parts, manual, pinout datasheet. Multiple 74148s can be cascaded by connecting EO of the high priority chip to EI of cascading the low priority chip ( see datasheet). Strobe ( enable) line provided for cascading ( N lines to n lines) High fan- out, low impedance. datasheet Input allows cascading for priority encoding on any number of input signals. 8- LINE TO 3- LINE PRIORITY ENCODER FAST SHOTTKY TTL J SUFFIX CERAMIC CASEN SUFFIX PLASTIC. 8- Line to 3- Line Priority Encoder. The SN74HC148D is a 8- to- 3 Priority Encoder features priority decoding of the inputs to ensure that only the highest- order data line is encoded.
