General description
The 74ABT16841A Bus interface latch is designed to provide extra data width for wider data/address paths of buses carrying parity.
The 74ABT16841A consists of two sets of ten D-type latches with 3-State outputs. The flip-flops appear transparent to the data when Latch Enable (nLE) is HIGH. This allows asynchronous operation, as the output transition follows the data in transition. On the nLE HIGH-to-LOW transition, the data that meets the set-up and hold time is latched.
Data appears on the bus when the Output Enable (nOE) is LOW. When nOE is HIGH the output is in the high-impedance state.
Features
- High speed parallel latches
- Live insertion/extraction permitted
- Extra data width for wide address/data paths or buses carrying parity
- Power-up 3-State
- Power-up reset
- Ideal where high speed, light loading, or increased fan-in are required with MOS microprocessors
- Output capability: +64 mA / ?32 mA
- Latch-up protection exceeds 500 mA per Jedec Std 17
- ESD protection exceeds 2000 V per MIL STD 883 Method 3015 and 200 V per Machine Model
