M74HC51B1屬于集成電路（IC）的門反相器-多功能可配置。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的M74HC51B1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(biāo)準(zhǔn)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(nèi)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(yīng)用的輸入以及任何未使用的輸入在驅(qū)動后的邏輯狀態(tài)，來配置所實現(xiàn)的整體邏輯功能。

DESCRIPTION

The M54/74HC51 is a high speed CMOS DUAL 2 WIDE-2 INPUT AND/OR INVERT GATE fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. It contains a 2-WIDE 2-INPUT AND-OR-INVERT GATE and a 2-WIDE 3-INPUT AND-OR-INVERT GATE.

■ HIGH SPEED tPD = 10 ns (TYP.) AT VCC = 5 V

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

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

■ OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS

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

■ BALANCED PROPAGATION DELAYS tPLH = tPHL

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

■ PIN AND FUNCTION COMPATIBLE WITH 54/74LS51
