CD74HC138-Q1 Overview
Key Features
- low power consumption usually associated with CMOS circuitry, yet has speeds comparable to low-power Schottky TTL logic
- The circuit has three binary select inputs (A0, A1, and A2)
- If the device is enabled, these inputs determine which one of the eight normally high outputs of the HC138 will go low
- Two active-low and one active-high enables (E1, E2, and E3) are provided to ease the cascading of decoders
- The decoder’s eight outputs can drive ten low-power Schottky TTL equivalent loads
