description

The 74ACT11238 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 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 74ACT11238 is characterized for operation from – 40°C to 85°C.
