74LVT162240A
FEATURES
•
16-bit bus interface
•
3-State buffers
•
Output capability: +12 mA/–12 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
resistors to hold unused inputs
DESCRIPTION
The 74LVT162240A is a high-performance BiCMOS product
designed for V
CC
operation at 3.3 V.
This device is an inverting 16-bit buffer that is ideal for driving bus
lines. The device features four Output Enables (1OE, 2OE, 3OE,
4OE), each controlling four of the 3-State outputs.
The 74LVT162240A is designed with 30
Ω
series resistance in both
the pull-up and pull-down output structures. This design reduces line
noise in applications such as memory address drivers, clock drivers,
and bus receivers/transmitters.
The 74LVT162240A is the same as the 74LVT16240A-1. The part
number has been changed to reflect industry standards.
•
Live insertion/extraction permitted
•
Outputs include series resistance of 30
Ω
making external
termination resistors unnecessary
•
Power-up 3-State
•
No bus current loading when output is tied to 5 V bus
•
Latch-up protection exceeds 500 mA per JEDEC Std 17
•
ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200 V per Machine Model
•
Same part as 74LVT16240A-1

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.
