Logic ICs 4.5V to 5.5V Operation Direct LSTTL Input Logic Compatibility,
VIL= 0.8V (Max), VIH = 2V (Min) CMOS Input Compatibility, Il ≤ 1µA at VOL, VOH The CD74HCT356 consists of data selectors/multiplexers that
select one of eight sources. The data select bits (S0, S1, and
S2) are stored in transparent latches that are enabled by a low
latch enable input (LE).
The data is stored in edge-triggered flip-flops that are
triggered by a low-to-high clock transition.
In both types the 3-state outputs are controlled by three
output-enable inputs (OE1, OE2, and OE3). Ordering Information
