The 74HC138D from Toshiba is a high-speed CMOS 3-to-8 line decoder/demultiplexer. Fabricated with silicon gate C2MOS technology, it offers high-speed operation similar to LSTTL while maintaining low CMOS power dissipation.
When enabled, the 3 binary select inputs (A, B, and C) determine which of the eight outputs (Y0-Y7) will go low. The device features multiple enable inputs (G1, G2A, G2B) for easy cascading and use in memory addressing systems. All inputs are protected against static discharge and transient overvoltage.
Key electrical characteristics include a wide operating voltage range of 2.0V to 6.0V and a typical propagation delay of 16 ns at 5V. The device consumes very low power, with a maximum supply current of 4.0 µA at 25°C. The outputs can source and sink 5.2mA.
Packaged in a 16-SOIC surface-mount format, the 74HC138D is suitable for various digital logic applications requiring efficient decoding or demultiplexing functions.
