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 including buffer output, which provides high noise immunity and stable output.

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 performance with the true CMOS low power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

■ HIGH SPEED:

tPD = 4.4ns (TYP.) at VCC = 3.3V

■ 5V TOLERANT INPUTS

■ INPUT VOLTAGE LEVEL:

VIL=0.8V, VIH=2V AT VCC=3V

■ LOW POWER DISSIPATION:

ICC = 2 µA (MAX.) at TA=25°C

■ LOW NOISE:

VOLP = 0.3V (TYP.) at VCC = 3.3V

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 4mA (MIN)

■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL

■ OPERATING VOLTAGE RANGE:

VCC(OPR) = 2V to 3.6V (1.2V Data Retention)

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 32

■ IMPROVED LATCH-UP IMMUNITY

■ POWER DOWN PROTECTION ON INPUTS

74LVX32TTR属于集成电路（IC） > 门和反相器。意法半导体（ST）集团制造生产的74LVX32TTR门和反相器逻辑栅极和逆变器系列中的产品对单个逻辑信号执行基本逻辑运算（例如 AND、NOT、OR 等）。与触发器不同，它们不能够存储信息，不会对提供给其输入的信号立即做出响应。虽然早就被集成电路实施形式所取代，以用于实现复杂功能，但分立栅极仍可在仅需要非常简单逻辑功能的情况下使用。
