Low-Voltage Quad Bus Buffer with 5-V Tolerant Inputs and Outputs

The TC74LCX126 is a high-performance CMOS quad bus buffers. Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation.

The device is designed for low-voltage (3.3 V) VCC applications, but it could be used to interface to 5-V supply environment for inputs.

This device requires the 3-state control input (OE) to be set high to place the output into the high impedance state.

All inputs are equipped with protection circuits against static discharge.

Features

• Low-voltage operation: VCC = 1.65 to 3.6 V

• High-speed operation: tpd = 6.0 ns (max) (VCC = 3.0 to 3.6 V)

• Ouput current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V)

• Latch-up performance: ＞± 500 mA

• Available in JEDEC SOP, JEITA SOP, TSSOP and VSSOP (US)

• Power-down protection is provided on all inputs and outputs

• Pin and function compatible with the 74 series (74AC/VHC/HC/F/ALS/LS etc.) 126 type
