74ABT841
Datasheet
General description
The 74ABT841 Bus interface register is designed to provide extra data width for wider data/address paths of buses carrying parity.
The 74ABT841 consists of ten D-type latches with 3-State outputs. The flip-flops appear transparent to the data when Latch Enable (LE) is High. This allows asynchronous operation, as the output transition follows the data in transition. On the LE High-to-Low transition, the data that meets the setup and hold time is latched.
Data appears on the bus when the Output Enable (OE) is Low. When OE is High the output is in the High-impedance state.
Features
- High speed parallel latches
- Extra data width for wide address/data paths or buses carrying parity
- Ideal where high speed, light loading, or increased fan-in are required with MOS microprocessors
- Slim DIP 300 mil package
- Broadside pinout
- Output capability: +64mA/-32mA
- Latch-up protection exceeds 500mA per Jedec Std 17
- ESD protection exceeds 2000 V per MIL STD 883 Method 3015 and 200 V per Machine Model
- Power-up 3-State
- Power-up reset
