FEATURES
74ALVT16543
DESCRIPTION
• 16-bit universal bus interface
• 5V I/O Compatible
• 3-State buffers
• Output capability: +64mA/-32mA
• TTL input and output switching levels
• Input and output interface capability to systems at 5V supply
• Bus-hold data inputs eliminate the need for external pull-up
The 74ALVT16543 is a high-performance BiCMOS product
designed for VCC operation at 2.5V or 3.3V with I/O compatibility up
to 5V. The device can be used as two 8-bit transceivers or one
16-bit transceiver.
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.
resistors to hold unused inputs
• 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
• ESD protection exceeds 2000V per MIL STD 883 Method 3015
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.
Control of data flow from B to A is similar, but using the nEBA,
nLEBA, and nOEBA inputs.
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.

NOTES:
1. All typical values are at VCC = 3.3V and Tamb = 25°C.
2. This is the increase in supply current for each input at the specified voltage level other than VCC or GND
3. This parameter is valid for any VCC between 0V and 1.2V with a transition time of up to 10msec. From VCC = 1.2V to VCC = 3.3V ± 0.3V a
transition time of 100µsec is permitted. This parameter is valid for Tamb = 25°C only.
4. Unused pins at VCC or GND.
5. ICCZ is measured with outputs pulled up to VCC or pulled down to ground.
6. For valid test results, data must not be loaded into the flip-flops (or latches) after applying power.
7. This is the bus hold overdrive current required to force the input to the opposite logic state.

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.
Application information — Applications that are described herein for any of these products are for illustrative purposes only. Philips
Semiconductors make no representation or warranty that such applications will be suitable for the specified use without further testing or
modification.

reasonably be expected to result in personal injury. Philips Semiconductors customers using or selling these products for use in such applications
do so at their own risk and agree to fully indemnify Philips Semiconductors for any damages resulting from such application.
Right to make changes — Philips Semiconductors reserves the right to make changes, without notice, in the products, including circuits, standard
cells, and/or software, described or contained herein in order to improve design and/or performance. Philips Semiconductors assumes no
responsibility or liability for the use of any of these products, conveys no license or title under any patent, copyright, or mask work right to these
