74LVT125

3.3 V quad buffer; 3-state

Rev. 05 — 10 February 2005

Product data sheet

1. General description

The LVT125 is a high-performance BiCMOS product designed for V_CCoperation at 3.3 V.

This device combines low static and dynamic power dissipation with high speed and high

output drive. The 74LVT125 device is a quad buffer that is ideal for driving bus lines. The

device features four output enable inputs (1OE, 2OE, 3OE and 4OE), each controlling one

of the 3-state outputs.

2. Features

■ Quad bus interface

■ 3-state buffers

■ Output capability: +64 mA and −32 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 and extraction permitted

■ No bus current loading when output is tied to 5 V bus

■ Power-up 3-state

■ Latch-up protection:

◆ JESD78: exceeds 500 mA

■ ESD protection:

◆ MIL STD 883 method 3015: exceeds 2000 V

◆ Machine model: exceeds 200 V
