M74HC51B1集成电路（IC）的门反相器-多功能可配置规格书PDF中文资料

M74HC51B1属于集成电路（IC）的门反相器-多功能可配置。由意法半导体集团制造生产的M74HC51B1门和反相器 - 多功能，可配置可配置逻辑栅极系列产品能以与标准逻辑栅极类似的方式，对单个逻辑信号执行基本逻辑运算，但并非局限于一个特定功能（例如 AND、NAND 等）。它们通常在内部使用少量逻辑门来实现，经过选择和互连后，以便通过选择操作数据所应用的输入以及任何未使用的输入在驱动后的逻辑状态，来配置所实现的整体逻辑功能。

DESCRIPTION

The M74HC51 is an high speed CMOS DUAL 2 WIDE 2 INPUT AND/OR INVERT GATE fabricated with silicon gate C2MOS technology. It contains a 2-WIDE 2-INPUT AND/OR INVERT GATE and a 2-WIDE 3-INPUT AND/OR INVERT GATE.

The internal circuit is composed of 3 stages (2 INPUT) or 5 stages (3 INPUT) including buffer output, which enables high noise immunity and stable output.

All inputs are equipped with protection circuits against static discharge and transient excess voltage.

■ HIGH SPEED: tPD = 11ns (TYP.) at VCC = 6V

■ LOW POWER DISSIPATION: ICC = 1µA(MAX.) at TA=25°C

■ HIGH NOISE IMMUNITY: VNIH = VNIL = 28 VCC (MIN.)

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN)

■ BALANCED PROPAGATION DELAYS: tPLH = tPHL

■ WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 51
