1998 Feb 27
853-1797 19025
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
74ABTH16841A incorporates bus-hold data inputs which
eliminate the need for external pull-up resistors to hold unused
inputs
Power-up reset
Ideal where high speed, light loading, or increased fan-in are
required with MOS microprocessors
Output capability: +64mA/–32mA
Latch-up protection exceeds 500mA per Jedec Std 17
ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200V per Machine Model
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 setup 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.
Two options are available, 74ABT16841A which does not have the
bus-hold feature and 74ABTH16841A which incorporates the
bus-hold feature.
