DESCRIPTION

The M54/74HC280 is a high speed CMOS 9-BIT PARITY GENERATOR fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low consumption.

■ HIGH SPEED

tPD = 22 ns (TYP.) at VCC = 5 V

■ LOW POWER DISSIPATION

ICC = 4 μA (MAX.) at TA = 25 °C 6 V

■ 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

54/74LS280

M74HC280RM13TR屬于集成電路（IC） > 奇偶校驗發(fā)生器和校驗器。意法半導(dǎo)體（ST）集團制造生產(chǎn)的M74HC280RM13TR奇偶校驗發(fā)生器和校驗器邏輯奇偶校驗發(fā)生器和校驗器系列器件是元件級器件，用于評估設(shè)置為 1 的數(shù)字字中的位數(shù)，并另外生成（或評估）一個奇偶校驗位，指示設(shè)置為 1 的字中的位數(shù)是偶數(shù)還是奇數(shù)。此功能通常用作檢測在傳輸過程中可能引入的數(shù)據(jù)錯誤的簡單方法。
