SN74HCS137 3- to 8-Line Decoder/Demultiplexer with Address Latches and Schmitt-

Trigger Inputs

1 Features

3 Description

•

Wide operating voltage range: 2 V to 6 V

Schmitt-trigger inputs allow for slow or noisy input

signals

Low power consumption

– Typical I_CCof 100 nA

– Typical input leakage current of ±100 nA

±7.8-mA output drive at 6 V

Extended ambient temperature range: –40°C to

+125°C, T_A

The SN74HCS137 is a three to eight decoder with

latched address inputs, one standard output strobe

(G₀), and one active low output strobe (G₁). When the

latch enable (LE) input is high, the device acts as a

standard three to eight decoder. When the latch

enable (LE) input is low, the address latch retains its

previous state. When the outputs are gated by either

strobe input, they are all forced into the high state.

When the outputs are not disabled by one or both of

the strobe inputs, only the selected output is low while

all others are high.

2 Applications

•

Memory device selection with shared data bus

Reduce required number of outputs for chip select

applications
