2003 Feb 21
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
• 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
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.
