High-Speed CMOS Logic 3-to-8-Line Decoder/Demultiplexer with Address Latches

The CD74HCT137E is a high-performance, silicon-gate CMOS device from Texas Instruments that combines the low power consumption of CMOS with the speed functionality akin to Low Power Schottky TTL. It is part of the HCT family, which is compatible with standard TTL integrated circuits. This decoder/demultiplexer features three binary select inputs (A, B, and C) and an active low enable input (E).

When the enable input (E) is high, all outputs (O0-O7) are low. When E is low, the binary select inputs determine which one of the eight outputs will go high, making this device ideal for hardware addressing and bit-selection tasks.
