HD74HC356 Datasheet 8-to-1-line Data Selectors/multiplexer/register(with 3-state Outputs)

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74HC356 8-to-1-line Data Selectors/Multiplexer/Register (with 3-state.

General Description

This data selectors/multiplexers contain full on-chip binary decoding to select one of eight data sources.

The data select address is stored in transparent latches that are enabled by a low level address on pin 11, Select Control.

Data on the 8 input lines is stored in a parallel input/output register which in the HD74HC356 is posed of 8 edge-triggered flip-flops, clocked by a low to high transition on pin 9, clock.
