Outputs Can Drive Up To 15 LSTTL Loads

Low Power Consumption, 80-μA Max ICC

Typical tpd = 11 ns

±6-mA Output Drive at 5 V

Low Input Current of 1 μA Max

description/ordering information

These data selectors/multiplexers contain inverters and drivers that supply full data selection to the four output

gates. A separate strobe (G) input is provided. A 4-bit word is selected from one of two sources and is routed

to the four outputs. The ’HC158 devices’ outputs provide inverted data.
