Texas Instruments Integrated Circuits (ICs) - Logic - Signal Switches, Multiplexers, Decoders SN74AHCT138DGVR

The SN74AHCT138DGVR is a 3-line to 8-line decoder/demultiplexer designed for high-speed memory decoding and data-routing applications. It features TTL-voltage compatible inputs and incorporates three enable inputs, which facilitate cascading and data reception without the need for additional external gates or inverters. This decoder is optimized for use in high-performance memory systems, ensuring that the propagation delay introduced is negligible when paired with fast enable circuits. The device operates within a supply voltage range of 4.5V to 5.5V and supports input and output voltage ranges from 0V to 5.5V. It has a high-level output current capability of -8 mA and a low-level output current capability of 8 mA. The operating temperature range is from -40¬8C to 85¬8C, making it suitable for various environmental conditions. The SN74AHCT138DGVR also offers robust latch-up performance and ESD protection, exceeding industry standards. This product is available in a 16-pin TVSOP package, making it compact for integration into space-constrained designs.
