2.5V/3.3V 20-bit bus interface latch (3-State)  
74ALVT16841  
FEATURES  
DESCRIPTION  
The 74ALVT16841 Bus interface latch is designed to provide extra  
data width for wider data/address paths of buses carrying parity. It is  
High speed parallel latches  
5V I/O Compatible  
designed for V operation at 2.5V or 3.3V with I/O compatibility to  
CC  
5V.  
Live insertion/extraction permitted  
The 74ALVT16841 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.  
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: +64mA/–32mA  
Latch-up protection exceeds 500mA per Jedec Std 17  
Bus-hold data inputs eliminate the need for external pull-up  
resistors to hold unused inputs  
ESD protection exceeds 2000V per MIL STD 883 Method 3015  
and 200V 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.

Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For  
detailed information see the relevant data sheet or data handbook.  
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one  
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or  
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended  
periods may affect device reliability.
