74LVT126
3.3 V quad buffer; 3-state
Rev. 04 — 11 February 2005
Product data sheet
1. General description
The LVT126 is a high-performance BiCMOS product designed for VCC operation at 3.3 V.
This device combines low static and dynamic power dissipation with high speed and high
output drive. The 74LVT126 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

[1] Typical values are measured at nominal VCC and Tamb = 25 °C.
[2] Unused pins at VCC or GND.
[3] This is the bus hold overdrive current required to force the input to the opposite logic state.
[4] This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms. From VCC = 1.2 V to VCC = 3.3 V ± 0.3 V
a transition time of 100 µs is permitted. This parameter is valid for Tamb = 25 °C only.
[5] Measured with outputs pulled up to VCC or GND.
[6] This is the increase in supply current for each input at the specified voltage level other than VCC or GND.
