1 General description

The 74LVT162240A is a high-performance BiCMOS product designed for VCC 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 enable pins (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 pulldown

output structures. This design reduces line noise in applications such as memory

address drivers, clock drivers, and bus receivers/transmitters.

2 Features and benefits

• 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:

– JESD17: exceeds 500 mA

• ESD protection:

– HBM JESD22-A114F exceeds 2000 V

– MM JESD22-A115-A exceeds 200 V
