DESCRIPTION
The 74VHCT03A is an advanced high-speed
CMOS QUAD 2-INPUT OPEN DRAIN NAND
GATE fabricated with sub-m icron sil icon gate and
double-layer metal wiring C
2
MOS technology.
The internal circuit is composed of 3 stages
including buffer ou tput, which provides high no ise
immunity and stable output.
This device can, with an external pull-up resistor,
be used in wired AND configuration. This d evice
can also be used as a led driver a nd in any other
application requiring a current sink.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
TSSOPSOP

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 stat ic discharge, giving
them 2KV ESD immunity and transient excess
voltage.

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
-40 to 85°C -55 to 125°C
= CPD x VCC x fIN + ICC/4 (per gate)
