CD54HC138 Product details

Description

The CDx4HC(T)138 and '238 are three to eight decoders with one standard output strobe (G2) and two active low output strobes (G 1 and G 0).

Features

Select one of eight data outputs:.
Active low for '138.
Active high for '238.
l/O port or memory selector.
Three enable inputs to simplify cascading.
Typical propagation delay of 13 ns at VCC = 5 V, CL = 15 pF, TA = 25°C.
Fanout (over temperature range).
Bus driver outputs: 15 LSTTL loads.
Standard outputs: 10 LSTTL loads.
Wide operating temp range: -55°C to 125°C.
Balanced propagation delay and t.
