DESCRIPTION

The 74VHCT86A is an advanced high-speed CMOS QUAD EXCLUSIVE OR GATE fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

Power down protection is provided on all inputs and outputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V since all inputs are equipped with TTL threshold.

All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

■ HIGH SPEED: tPD = 5.5ns (TYP.) at VCC = 5V

■ LOW POWER DISSIPATION:

ICC = 2 µA (MAX.) at TA=25°C

■ COMPATIBLE WITH TTL OUTPUTS:

VIH = 2V (MIN.), VIL = 0.8V (MAX)

■ POWER DOWN PROTECTION ON INPUTS & OUTPUTS

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 8 mA (MIN)

■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL

■ OPERATING VOLTAGE RANGE:

VCC(OPR) = 4.5V to 5.5V

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 86

■ IMPROVED LATCH-UP IMMUNITY

■ LOW NOISE: VOLP = 0.8V (MAX.)

74VHCT86A属于集成电路（IC） > 门和反相器。意法半导体（ST）集团制造生产的74VHCT86A门和反相器逻辑栅极和逆变器系列中的产品对单个逻辑信号执行基本逻辑运算（例如 AND、NOT、OR 等）。与触发器不同，它们不能够存储信息，不会对提供给其输入的信号立即做出响应。虽然早就被集成电路实施形式所取代，以用于实现复杂功能，但分立栅极仍可在仅需要非常简单逻辑功能的情况下使用。
