FEATURES
DESCRIPTION
The 74ABT16841A Bus interface latch is designed to provide extra
data width for wider data/address paths of buses carrying parity.
• High speed parallel latches
• Live insertion/extraction permitted
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.
• 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
Data appears on the bus when the Output Enable (nOE) is LOW.
When nOE is HIGH the output is in the high-impedance state.
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

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 °C.
3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

NOTES:
1. Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
2. This is the increase in supply current for each input at 3.4 V.
3. For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power.
4. This parameter is valid for any V between 0 V and 2.1 V with a transition time of up to 10 msec. From V = 2.1 V to V = 5 V ± 10% a
