74ABT823
Datasheet
General description
The 74ABT823 bus interface register is designed to eliminate the extra packages required to buffer existing registers and provide extra data width for wider data and address paths of buses carrying parity.
The 74ABT823 is a 9-bit wide buffered register with clock enable input (CE) and master reset input (MR) which are ideal for parity bus interfacing in systems using many microprocessors.
The register is fully edge-triggered. The state of each D input, one set-up time before the LOW-to-HIGH clock transition, is transferred to the corresponding output Q of the flip-flop.
Features
- High-speed parallel registers with positive edge-triggered D-type flip-flops
- Ideal where high speed, light loading, or increased fan-in are required with MOS microprocessors
- Output capability: +64 mA and -32 mA
- Latch-up protection:
- JESD78: exceeds 500 mA
- ESD protection:
- MIL STD 883 method 3015: exceeds 2000 V
- Machine model: exceeds 200 V
- Power-on 3-state
- Power-on reset
