DESCRIPTION

The 74LCX05 is a low voltage CMOS OPEN
DRAIN HEX INVERTER fabricated with
sub-micron silicon gate and double-layer metal
wiring C

2

MOS technology. It is ideal for low power
and high speed 3.3V applications. It can be
interfaced to 5V signal environment for inputs.

The internal circuit is composed of 3 stages
including buffer ou tput, which provides high noise
immunity and stable output.
It has same speed performance at 3. 3V than 5V
AC/ACT family, combined with a lower power
consumption.
All inputs and outputs are equipped with
protection circuits against stat ic discharge, giving
them 2KV ESD immunity and transient excess
voltage.

2) Param eter guaranteed by design

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/6 (per gate)
