CD74HC126E .

The CD74HC126E is a high speed CMOS logic Quad Buffer with 3-state outputs. It contains four independent three-state buffers, each having its own output enable input, which when low puts the output in the high-impedance state.

• Separate output enable inputs
• Balanced propagation delay and transition times
• Significant power reduction compared to LSTTL logic Ics
• High noise immunity - NIL = 30%, NIH = 30% of VCC at VCC = 5V
