74HC125D - Quad Bus Buffer

Description

2.

The 74HC125D,74HC126D are high speed CMOS QUAD BUS BUFFERs fabricated with silicon gate C2MOS technology.

Features

  • (1) High speed: tpd = 10 ns (typ. ) at VCC = 6.0 V (2) Low power dissipation: ICC = 4.0 µA (max) at Ta = 25  (3) Balanced propagation delays: tPLH ≈ tPHL (4) Wide operating voltage range: VCC(opr) = 2.0 to 6.0 V 4.

Functional Description • Quad Bus Buffer, Non-Inverted 3-State Outputs 74HC125D: Quad Bus Buffer 74HC126D: Quad Bus Buffer 2. General The 74HC125D,74HC126D are high speed CMOS QUAD BUS BUFFERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The 74HC125D requires the 3-state control input G to be set high to place the output into the high impedance state, whereas the 74HC126D requires the control input to be set low to place the output into high impedance. All inputs are equipped with protection circuits against static discharge or transient excess voltage. 3.
