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).

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.
