Philips Semiconductors Product specification

74ABT126Quad buffer (3-State)

FEA TURES

•Quad bus interface

•3-State buffers

•Live insertion/extraction permitted

•Output capability: +64mA/–32mA

•Latch-up protection exceeds 500mA per JEDEC Std 17

DESCRIPTION

The 74ABT126 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.

The 74ABT126 device is a quad buffer that is ideal for driving bus
lines. The device features four Output Enables (OE0, OE1, OE2,
OE3), each controlling one of the 3-State outputs.

•ESD protection exceeds 2000V per MIL STD 883 Method 3015

and 200V per Machine Model

•Power-up 3-State

•Inputs are disabled during 3-State mode

device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability .

2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.

3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
