General Description

HD74HC148 encodes eight data lines to three-line (4-2-1) binary (octal).

Cascading circuitry (enable input EI and enable output EO) is provided to allow octal expansion without the need for external circuitry.

The data inputs and outputs are active at the low logic level.

Key Features

High Speed Operation: tpd (0 - 7 to A0 - A2) = 15 ns typ (CL = 50 pF).
High Output Current: Fanout of 10 LSTTL Loads.
Wide Operating Voltage: VCC = 2 to 6 V.
Low Input Current: 1 µA max.
Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C).
