DESCRIPTION

The 74VHCT86A is an advanced high-speed CMOS QUAD EXCLUSIVE OR GAT E fabricated with sub-micron silicon gate and double-layer metal wiring C

2

MOS 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 us ed to interf ac e 5V to 3V since al l inputs are equipped with TTL threshold. All inputs and outputs are equipped with protection circuits against stat ic discharge, giving them 2KV ESD immunity and transient excess voltage.

CAPACITIVE CHARACTERISTICS

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without

load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. I

CC(opr)

= CPD x VCC x fIN + ICC/4 (per gate)
