The SN74HCT138N from Texas Instruments is a high-speed 3-line to 8-line decoder/demultiplexer designed for memory decoding and data routing applications. It features an operating voltage range of 4.5 V to 5.5 V and can drive up to 10 LSTTL loads. With a low power consumption of 80 µA maximum ICC and a typical propagation delay of 17 ns, this device is suitable for high-performance systems.
The SN74HCT138N incorporates three enable inputs, simplifying cascading and data reception. Its inputs are TTL-voltage compatible, and it offers an output drive of ±4 mA at 5 V. The low input current of 1 µA maximum further contributes to its efficiency.
This component is available in a 16-PDIP (Plastic Dual In-line Package) with through-hole mounting. The package dimensions are 19.31 mm x 6.35 mm. Its operating temperature range is -40°C to 85°C, making it suitable for various environmental conditions.
The SN74HCT138N is designed to minimize system decoding delays, especially when used with high-speed memories. Its negligible system delay makes it an effective component in fast memory systems and data transmission applications.
