The document describes M74HC238, a high-speed CMOS 3-to-8 line decoder fabricated with silicon gate C2MOS technology. It features high speed, low power dissipation, high noise immunity, symmetrical output impedance, balanced propagation delays, and a wide operating voltage range.
The M74HC238 is a high-speed CMOS 3-to-8 line decoder fabricated with silicon gate C2MOS technology. It features three binary select inputs (A, B, and C) to determine which of the eight outputs goes high when enabled. The device includes three enable inputs (G1, G2A, G2B) to facilitate cascade connections and applications in memory systems, with all inputs protected against static discharge and transient excess voltage.
| Propagation Delay (Typical) | 15ns |
|---|---|
| Supply Voltage Range | 2V to 6V |
| Quiescent Supply Current (Max) | 4µA |
| Operating Temperature Range | -55 to 125 °C |
| Number of Outputs | 8 |
Three enable inputs are provided to ease cascade connection and application of this address decoder in memory systems.
Yes, the device is pin and function compatible with the 74 series.
All inputs are equipped with protection circuits against static discharge and transient excess voltage.
