MC74HC137N
1-of-8 Decoder/Demultiplexer with Address Latch
SEMICONDUCTOR TECHNICAL DATA " -
High–Performance Silicon–Gate CMOS

The MC74HC137 is identical in pinout to the LS137. The device inputs are
compatible with standard CMOS outputs; with pullup resistors, they are
compatible with LSTTL outputs.
The HC137 decodes a three–bit Address to one–of–eight active–low
outputs. The device has a transparent latch for storage of the Address. Two
Chip Selects, one active–low and one active–high, are provided to facilitate
the demultiplexing, cascading, and chip–selecting functions.
The demultiplexing function is accomplished by using the Address inputs
to select the desired device output, and then by using one of the Chip
Selects as a data input while holding the other one active.
The HC137 is the inverting version of the HC237. Output Drive Capability: 10 LSTTL Loads Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2 to 6 V Low Input Current: 1 μA High Noise Immunity Characteristic of CMOS Devices In Compliance with the Requirements Defined by JEDEC Standard
No. 7A Chip Complexity: 152 FETs or 38 Equivalent Gates
