SN74LVC138APWR Description

Short technical summary and product information.

The SN74LVC138APWR from Texas Instruments is a 3-Line to 8-Line decoder/demultiplexer designed for high-performance 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 systems requiring minimal decoding delay. It features a typical output ground bounce of less than 0.8V and output VOH undershoot greater than 2V at 3.3V and 25°C. Latch-up performance exceeds 250 mA per JESD 17.

 

The SN74LVC138APWR is available in a 16-TSSOP package, designed for surface mounting. Its high-speed capabilities minimize system decoding effects, making the effective system delay negligible when used with high-speed memories.
