The GD74LS138 is a member of the '74xx' family of TTL logic gates, specifically designed for decoding or demultiplexing applications. It offers a 3-input to 8-output configuration, making it suitable for high-performance memory decoding or data routing where short propagation delays are critical. The chip includes three enable pins (two active-low and one active-high) which simplify cascading without external inverters.
This device operates with a supply voltage ranging from 1.0V to 5.5V and has a typical propagation delay of 21ns. Its low power consumption is rated at 32mW, and it operates within a temperature range of -40°C to +125°C. The GD74LS138 is designed for high speed and features Schottky diode clamping on its inputs to suppress line ringing and simplify system design.
Applications for the GD74LS138 include line decoding, server systems, digital systems, line demultiplexing, telecommunication circuits, and memory circuits. It is typically available in a Through Hole package.
