2.5V/3.3V 16-bit bus transceiver (3-State)
74ALVT16646
FEATURES
• 16-bit universal bus interface
• 5V I/O Compatible
DESCRIPTION
The 74ALVT16646 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
This device is a 16-bit transceiver featuring non-inverting 3-State
bus compatible outputs in both send and receive directions. The
control function implementation minimizes external timing
requirements. The device features an Output Enable (OE) input for
easy cascading and a Direction (DIR) input for direction control.
• 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
Data on the A or B bus is clocked into the registers on the Low to
High transition of the appropriate clock (CPAB or CPBA). The
select-control (SAB and SBA) inputs can multiplex stored and
real-time (transparent mode data).
resistors to hold unused inputs
• Live insertion/extraction permitted
• No bus current loading when output is tied to 5V bus
• Power-up reset
• Power-up 3-State
• 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 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.
