1. General description
The 74LVC841A is a high performance, low-power, low-voltage Si-gate CMOS device and
superior to most advanced CMOS compatible TTL families.
Inputs can be driven from either 3.3 Vor 5 V devices. In 3-state operation, outputs can
handle 5 V. This feature allows the use of these devices as translators in a mixed
3.3 Vand 5 V environment.
The 74LVC841A is a 10-bit transparent latch featuring separate D-type inputs for each
latch and 3-state outputs for bus-oriented applications. A latch enable (pin LE) input and
an output enable (pin OE) input are common to all internal latches. The 74LVC841A
consists of ten transparent latches with 3-state true outputs. When pin LE is HIGH, data at
the Dn inputs enters the latches. In this condition the latches are transparent, i.e., a latch
output will change each time its corresponding D-input changes. When pin LE is LOW the
latches store the information that was present at the D-inputs a set-up time preceding the
HIGH-to-LOW transition of pin LE. When pin OE is LOW, the contents of the ten latches
are available at the outputs. When pin OE is HIGH, the outputs go to the high-impedance
OFF-state. Operation of the pin OE input does not affect the state of the latches.

VM = 1.5 V at VCC 2.7 V;
VM = 0.5 × VCC at VCC < 2.7 V;
VX = VOL + 0.3 V at VCC 2.7 V;
VX = VOL + 0.1 × VCC at VCC < 2.7 V;
VY = VOH 0.3 V at VCC 2.7 V;
VY = VOH 0.1 × VCC at VCC < 2.7 V.
VOL and VOH are typical output voltage drop that occur with the output load.

[1] The circuit performs better when RL = 1000 .
Test data is given in Table 9.
Definitions for test circuits:
RL= Load resistor.
CL= Load capacitance including jig and probe capacitance.
RT= Termination resistance should be equal to the output impedance Zo of the pulse
generator.

15. Data sheet status
[1] Please consult the most recently issued data sheet before initiating or completing a design.
[2] The product status of the device(s) described in this data sheet may have changed since this data sheet was published. The latest information is available on the Internet at
URL http://www.semiconductors.philips.com.
[3] For data sheets describing multiple type numbers, the highest-level product status determines the data sheet status.
16. Definitions
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 60134). 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.
