SN74LVC138APWT Description

Short technical summary and product information.

The Texas Instruments SN74LVC138APWT is a high-performance 3-line to 8-line decoder/demultiplexer designed for memory-decoding and data-routing applications. It operates within a voltage range of 1.65V to 3.6V, with inputs capable of accepting voltages up to 5.5V.

 

This device boasts a maximum propagation delay of 5.8 ns at 3.3V, making it suitable for high-speed systems where minimizing decoding delay is crucial. The SN74LVC138APWT minimizes the effects of system decoding, ensuring that the effective system delay introduced by the decoder is negligible when used with fast memories.

 

Packaged in a 16-TSSOP, the SN74LVC138APWT is designed for surface mounting. It operates across a temperature range of -40°C to 85°C and has a typical supply current of 10 µA. Latch-up performance exceeds 250 mA per JESD 17.
