The SN74HCT138PW from Texas Instruments is a high-speed 3-line to 8-line decoder/demultiplexer designed for memory decoding and data routing applications. It features a wide operating voltage range of 4.5 V to 5.5 V, making it suitable for various system designs.
This device offers a typical propagation delay of 17 ns and outputs capable of driving up to 10 LSTTL loads with ±4 mA of drive at 5 V. Its low power consumption, with a maximum ICC of 80 µA, and low input current of 1 µA max, contribute to efficient system operation.
The SN74HCT138PW incorporates three enable inputs, which simplify cascading and data reception tasks. It is housed in a 16-TSSOP surface-mount package, measuring 5.00 mm x 4.40 mm, and operates within a temperature range of -40°C to 85°C.
This decoder/demultiplexer is well-suited for high-performance memory systems where minimizing decoding delay is critical. Its design ensures that the effective system delay introduced by the decoder is negligible when used with fast enable circuits.
