M74HC51集成電路（IC）的門反相器-多功能可配置規(guī)格書PDF中文資料

M74HC51屬于集成電路（IC）的門反相器-多功能可配置。由意法半導體集團制造生產(chǎn)的M74HC51門和反相器 - 多功能，可配置可配置邏輯柵極系列產(chǎn)品能以與標準邏輯柵極類似的方式，對單個邏輯信號執(zhí)行基本邏輯運算，但并非局限于一個特定功能（例如 AND、NAND 等）。它們通常在內部使用少量邏輯門來實現(xiàn)，經(jīng)過選擇和互連后，以便通過選擇操作數(shù)據(jù)所應用的輸入以及任何未使用的輸入在驅動后的邏輯狀態(tài)，來配置所實現(xiàn)的整體邏輯功能。

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
