74LVX32屬于集成電路（IC）的轉(zhuǎn)換器電平移位器。由意法半導(dǎo)體集團制造生產(chǎn)的74LVX32轉(zhuǎn)換器，電平移位器邏輯轉(zhuǎn)換器或電平移位器 IC 可用于在數(shù)字邏輯設(shè)備之間傳遞信息，這些設(shè)備可在不同/不兼容的供電電壓下工作，或可實現(xiàn)不同的信令方式。例如，可以將需要 5 V 電源的數(shù)字輸出傳感器連接到具有 3.3 V I/O 電源的 FPGA，或者在 CMOS 或 TTL 等單端信令方式與 PECL 或 LVDS 等差分技術(shù)之間進行轉(zhuǎn)換。

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:
