description

The ’HCT138 are designed for high-performance

memory-decoding or data-routing applications

requiring very short propagation delay times. In

high-performance memory systems, these

decoders can minimize the effects of system

decoding. When employed with high-speed

memories utilizing a fast enable circuit, the delay

timesofthesedecodersandtheenabletimeofthe

memory are usually less than the typical access

time of the memory. This means that the effective

system delay introduced by the decoders is

negligible.

NC – No internal connection

The conditions at the binary-select inputs and the three enable inputs select one of eight output lines. Two

active-low (G) and one active-high (G) enable inputs reduce the need for external gates or inverters when

expanding. A 24-line decoder can be implemented without external inverters and a 32-line decoder requires

only one inverter. An enable input can be used as a data input for demultiplexing applications.

The SN54HCT138 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74HCT138 is characterized for operation from –40°C to 85°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
