Important notice
Dear Customer,
On 7 February 2017 the former NXP Standard Product business became a new company with the
tradename Nexperia. Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS
semiconductors with its focus on the automotive, industrial, computing, consumer and wearable
application markets
In data sheets and application notes which still contain NXP or Philips Semiconductors references, use
the references to Nexperia, as shown below.
Instead of http://www.nxp.com, http://www.philips.com/ or http://www.semiconductors.philips.com/,
use http://www.nexperia.com
Instead of sales.addresses@www.nxp.com or sales.addresses@www.semiconductors.philips.com, use

2.5 V/3.3 V 16-bit registered transceiver (3-State)
FEATURES
74ALVT16543
DESCRIPTION
• 16-bit universal bus interface
• 5 V I/O Compatible
• 3-State buffers
• Output capability: +64 mA/–32 mA
• TTL input and output switching levels
• Input and output interface capability to systems at 5 V 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 2.5 V or 3.3 V with I/O compatibility
up to 5 V. 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 5 V bus
• Latch-up protection exceeds 500mA per JEDEC Std 17
• ESD protection exceeds 2000 V 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 200 V 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 = 3.3 V 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 0 V and 1.2 V with a transition time of up to 10 msec. From VCC = 1.2 V to VCC = 3.3 V ± 0.3 V
a transition time of 100 µsec 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.
