2.5V/3.3V 16-bit registered transceiver (3-State)  
74ALVT16953  
FEATURES  
Two 8-bit registered transceivers  
5V I/O Compatible  
DESCRIPTION  
The 74ALVT16953 is a high-performance BiCMOS product  
designed for V operation at 2.5V or 3.3V with I/O compatibility up  
CC  
to 5V.  
3-State buffers  
The 74ALVT16953 is a dual octal registered inverting transceiver.  
Two 8-bit registers store data flowing in both directions between two  
bidirectional buses. Data applied to the inputs is entered and stored  
on the rising edge of the Clock (nCPXX) provided that the Clock  
Enable (nCEXX) is Low. The data is then present at the 3-State  
output buffers, but is only accessible when the Output Enable  
(nOEXX) is Low. Data flow from A inputs to B outputs is the same as  
for B inputs to A outputs.  
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  
resistors to hold unused inputs  
Live insertion/extraction permitted  
Power-up 3-State  
Active bus hold circuitry is provided to hold unused or floating data  
inputs at a valid logic level.  
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  
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.
