FEATURES
DESCRIPTION
• 16-bit universal bus interface
The 74ALVT16543 is a high-performance BiCMOS product
designed for V operation at 2.5V or 3.3V with I/O compatibility up
• 5V I/O Compatible
CC
to 5V. The device can be used as two 8-bit transceivers or one
16-bit transceiver.
• 3-State buffers
• Output capability: +64mA/-32mA
• TTL input and output switching levels
• Input and output interface capability to systems at 5V supply
The 74ALVT16543 contains two sets of eight D-type latches, with
separate control pins for each set. Using data flow from A to B as an
example, when the A-to-B Enable (nEAB) input and the A-to-B Latch
Enable (nLEAB) input are Low, the A-to-B path is transparent.
• Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
A subsequent Low-to-High transition of the nLEAB signal puts the A
data into the latches where it is stored and the B outputs no longer
change with the A inputs. With nEAB and nOEAB both Low, the
3-State B output buffers are active and display the data present at
the outputs of the A latches.
• Live insertion/extraction permitted
• Power-up 3-State
• Power-up reset
• No bus current loading when output is tied to 5V bus
• Latch-up protection exceeds 500mA per JEDEC Std 17
Control of data flow from B to A is similar, but using the nEBA,
nLEBA, and nOEBA inputs.
• ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200V per Machine Model
Active bus-hold circuitry is provided to hold unused or floating data
inputs at a valid logic level.

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 negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.

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 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.
