DESCRIPTION
The 74LVX32 is a low voltage CMOS QUAD
2-INPUT OR GATE fabricated with sub-micron
silicon gate and double-layer metal wiring C2MOS
technology. It is ideal for low power, battery
operated and low noise 3.3V applications.
The internal circuit is composed of 2 stages
includin g bu ffer output, which prov id es hig h noise
immunity and stable outpu t.
Power down protection is provided on all inputs
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
system. It combines high speed pe rformance with
the t rue CMOS l ow power consumption. All inputs
and outputs are equipped with protection circuits
against static discharge, giving them 2KV ESD
immunity and transient exces s voltage.

Table 8: AC Electrical Characteristics (Input tr = tf = 3ns)
1) Skew is def ined as the absolut e value of the dif ference between the actual propagation delay for any two outputs of the s ame device switch-
in g i n the same di rectio n, either HIGH or LO W
2) Parameter guarante ed by design
(*) Voltage range is 3.3V ± 0.3V
Table 9: Capacitive Characteristics
1) C PD 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 V CC x fIN + ICC/4 (per gate)
