TSSOP14
Description
■
Pin and function compatible with
74 series 05
■
Latch-up performance exceeds
500mA (JESD 17)
The 74LCX05 is a low voltage CMOS open drain
HEX inverter fabricated with sub-micron silicon
gate and double-layer metal wiring C2MOS
technology. It is ideal for low power and high
speed 3.3V applications. It can be interfaced to
5V signal environment for inputs.
■
ESD performance:
– HBM > 2000V
(MIL STD 883 method 3015); MM > 200V
The internal circuit is composed of 3 stages
including buffer output, 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 static discharge, giving
them 2KV ESD immunity and transient excess
voltage.

Maximum rating
Maximum rating
stressing the device above the rating listed in the “absolute maximum ratings” table may
cause permanent damage to the device. these are stress ratings only and operation of the
device at these or any other conditions above those indicated in the operating sections of
this specification is not implied. exposure to absolute maximum rating conditions for
extended periods may affect device reliability. refer also to the STMicroelectronics sure
program and other relevant quality documents.

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. ICC(opr) = CPD x VCC x fIN + ICC/6 (per gate)
