description

The ′AC11238 circuit is designed to be

used in high-performance memory-decoding or

data-routing applications requiring very short

propagation delay times. In high-performance

memory systems, this decoder can be used to

minimize the effects of system decoding. When

employed with high-speed memories utilizing a

fast enable circuit, the delay times of this decoder

9 10 11 12 13

NC – No internal connection

and the enable time of the memory are usually less than the typical access time of the memory. This means that

the effective system delay introduced by the decoder is negligible.

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

active-low and one active-high 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 54AC11238 is characterized for operation over the full military temperature range of – 55°C to 125°C. The

74AC11238 is characterized for operation from – 40°C to 85°C.

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.
