74ABT126D

74ABT126 Quad buffer 3-state Rev. 04 17 February 2005 Product data sheet 1. General 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 enable inputs (nOE each controlling one of the 3-state outputs (nY). 2. Features Quad bus interface 3-state buffers Live insertion and extraction permitted Output capability: +64 mA and - 32 mA Inputs are disabled during 3-state mode 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 3.
