74LVT125; 74LVTH125
3.3 V quad buffer; 3-state
Rev. 7 — 31 May 2016
Product data sheet
1. General description
The 74LVT125; 74LVTH125 is a high-performance BiCMOS product designed for V
CC
operation at 3.3 V.
This device combines low static and dynamic power dissipation with high speed and high
output drive. The 74LVT125; 74LVTH125 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 and benefits
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 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

5. Pinning information
5.1 Pinning
(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.

The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability.
