74LS848 datasheet


Description :

The SN54LS348 / 74LS348 and the SN54348 / SN74848 are eight input priority encoders which provide the 8-line to 3-line function. Theoutputs (A0–A2) and inputs (0– 7) are active low. The active low input whichhas the highest priority (input 7 has the highest) is represented on the outputs(output A0 is the lowest bit). An example would be if inputs 1, 2 and 4 were low, then a binary 4 would be represented on the outputs. The GS (Group Signal) output is active low when any of the inputs are low. It serves to indicate when any of the inputs are active. A0, A1 and A2 are three-state outputs. This allows for up to 64 line expansion without the need for special external circuitry.

HD74HC147 Datasheet PDF – 10-to-4-line Priority Encoder

Part Number : HD74HC147

Function : 10-to-4-line Priority Encoder

Package : DIP, SOP 16 Pin

Manufacturers : Renesas Electronics

Pinouts :

HD74HC147 datasheet


Description :

The HD74HC147 features priority encoding of the inputs to ensure that only the highest order data line is encoded. Nine input lines are encoded to a four line BCD output. The implied decimal zero condition requires no input condition as zero is encoded when all nine data lines are at a high logic level. All data inputs and outputs are active at the low logic level.


1. High Speed Operation : tpd = 14.5 ns typ (CL = 50 pF)
2. High Output Current : Fanout of 10 LSTTL Loads
3. Wide Operating Voltage : VCC = 2 to 6 V
4. Low Input Current : 1 μA max
5. Low Quiescent Supply Current : ICC (static) = 4 μA max (Ta = 25°C)
