2.5V/3.3V 16-bit transceiver
with 30Ω termination resistors (3-State)
74ALVT162245
FEATURES
• 16-bit bidirectional bus interface
• 3-State buffers
DESCRIPTION
The 74ALVT162245 is a high-performance BiCMOS product
designed for V operation at 2.5V or 3.3V with I/O compatibility up
CC
to 5V.
• 5V I/O compatibile
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 (nOE) input for
easy cascading and a Direction (DIR) input for direction control.
• Output capability: +12mA/-12mA
• 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 74ALVT162245 is designed with 30Ω series resistance in both
the High and Low states of the output. This design reduces line
noise in applications such as memory address drivers, clock drivers,
and bus transceivers/transmitters.
resistors to hold unused inputs
• Live insertion/extraction permitted
• Outputs include series resistance of 30Ω making external
termination resistors unnecessary
• Power-up 3-State
• 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 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.
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.
Disclaimers
