The 74LVC16373A and 74LVCH16373A are 16-bit D-type transparent latches featuring separate D-type inputs with bus hold (74LVCH16373A only) for each latch and 3-state outputs for bus-oriented applications. One Latch Enable (LE) input and one Output Enable (OE) are provided for each octal. Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to the outputs. These features allow the use of these devices in mixed 3.3 V and 5 V applications.
The NXP 74LVC16373A and 74LVCH16373A are 16-bit D-type transparent latches designed for bus-oriented applications. They feature separate D-type inputs with optional bus hold (74LVCH16373A only) and 3-state outputs. The devices support mixed 3.3 V and 5 V applications, with inputs drivable from either voltage level and outputs capable of withstanding up to 5.5 V when disabled.
| Supply voltage range | 1.2 V to 3.6 V |
|---|---|
| Input voltage tolerance | 5 V tolerant |
| Output voltage tolerance (disabled) | 5.5 V |
| Operating temperature range | -40 °C to +125 °C |
The 74LVCH16373A includes separate D-type inputs with bus hold for each latch, which the 74LVC16373A does not have.
Yes, inputs can be driven from either 3.3 V or 5 V devices, and outputs can withstand up to 5.5 V when disabled.
When OE is LOW, the latch contents are available at the outputs; when OE is HIGH, the outputs go to the high impedance OFF-state.
