The HD74ALVCHS162830 is a 1-bit to 2-bit address driver designed for 2.3 V to 3.6 V VCC operation. The driver has a high output current of ±12 mA (@VCC=3.0 V) and can eliminate the need for external pull-up/pull-down resistors on the data inputs. The driver also has diodes to clamp overshoot.
The Hitachi HD74ALVCHS162830 address driver converts a single input bit to a two‑bit address with three‑state outputs. It operates from 2.3 V to 3.6 V supply, provides active bus‑hold on inputs, and each output can sink up to 12 mA.
The datasheet details absolute maximum ratings, recommended operating conditions, pin assignments, electrical and switching characteristics, as well as package dimensions and cautions for use in safety‑critical applications.
| Supply voltage range | 2.3 V to 3.6 V |
|---|---|
| Maximum output current per pin | 12 mA |
| High output current (typical) | +12 mA @ Vcc=3.0 V |
| Bus‑hold feature | Eliminates external pull‑up/pull‑down resistors |
It operates with a supply voltage between 2.3 V and 3.6 V.
Each output can sink up to 12 mA.
The bus‑hold circuit keeps unused inputs at a valid logic level, removing the need for external resistors.
The input voltage may range from –0.5 V to +4.6 V.
