Texas Instruments SN74LVC138A 3-Line To 8-Line decoder/Demultiplexer SN74LVC138APWE4

The SN74LVC138A 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 1.65 V to 3.6 V and can accept input voltages up to 5.5 V. The device features a maximum propagation delay of 5.8 ns at 3.3 V, making it suitable for applications requiring minimal delay. Typical output ground bounce is less than 0.8 V, and output undershoot is greater than 2 V at 3.3 V under specified conditions. This decoder is particularly useful in systems where high-speed memory access is critical, as it minimizes the impact of decoding delays. The SN74LVC138A is available in various package types, including TSSOP, and is suitable for applications such as LED displays, servers, and factory automation. Its latch-up performance exceeds 250 mA per JESD 17, ensuring reliability in demanding environments.
