Texas SN74LS148N 8-to-3 Priority Encoder DIL16

Manufactured by Texas Instruments - SN74LS148N - DIL16 through hole package.

The SN74LS148N is a 8-to-3 Priority Encoder features priority decoding of the inputs to ensure that only the highest-order data line is encoded. Encode 8 Data Lines to 3-Line Binary (Octal). The implied decimal zero condition requires no input condition as zero is encoded when all nine data lines are at a high logic level. Cascading circuitry (enable input E1 and enable output E0) has been provided to allow octal expansion without the need for external circuitry. For all types, data inputs and outputs are active at the low logic level.
