This document describes the features and characteristics of the 74ABT16841A and 74ABTH16841A, which are 20-bit bus interface latches with 3-State outputs. They are ideal for applications requiring high speed, light loading, or increased fan-in with MOS microprocessors.
This document is a product specification datasheet for the Philips 74ABT16841A and 74ABTH16841A, which are 20-bit bus interface latches featuring 3-State outputs. The devices consist of two sets of ten D-type latches designed to provide extra data width for wider data/address paths or buses carrying parity. They are suitable for use with MOS microprocessors where high speed, light loading, or increased fan-in are required.
| Data width | 20-bit |
|---|---|
| Output capability | +64mA/-32mA |
| Latch-up protection | exceeds 500mA |
| ESD protection | exceeds 2000V |
| Operating temperature range | -40°C to +85°C |
| Package type | 56-Pin Plastic SSOP or TSSOP |
The 74ABTH16841A incorporates bus-hold data inputs which eliminate the need for external pull-up resistors, whereas the 74ABT16841A does not have this feature.
Each device consists of two sets of ten D-type latches with 3-State outputs.
