M74HC573M1R集成電路（IC）的鎖存器規(guī)格書PDF中文資料

M74HC573M1R屬于集成電路（IC）的鎖存器。由意法半導體集團制造生產的M74HC573M1R鎖存器鎖存器是類似于觸發(fā)器的基本數字存儲設備，但是不同之處在于，在鎖存使能（或類似命名）信號處于有效邏輯狀態(tài)的任何時間，保持的邏輯狀態(tài)都可以改變?！巴该鳌辨i存器還允許設備輸出在鎖存使能信號有效時反映輸入的當前狀態(tài)，而相反的是，狀態(tài)僅在保持狀態(tài)已固定時改變。

DESCRIPTION

The M54/74HC563 and M54HC573 are high speed CMOS OCTAL LATCH WITH 3-STATE OUTPUTS fabricated with in silicon gate C2MOS technology.

These ICs archive the high speed operation similar to equivalent LSTTL while maintaning the CMOS low power dissipation.

■ HIGH SPEED

tPD = 13 ns (TYP.) AT VCC = 5 V

■ LOW POWER DISSIPATION

ICC = 4 μA (MAX.) AT TA = 25 °C

■ HIGH NOISE IMMUNITY

VNIH = VNIL = 28 VCC (MIN.)

■ OUTPUT DRIVE CAPABILITY

15 LSTTL LOADS

■ SYMMETRICAL OUTPUT IMPEDANCE

IOL = |IOH|?= 6 mA (MIN.)

■ BALANCED PROPAGATION DELAYS

tPLH = tPHL

■ WIDE OPERATING VOLTAGE RANGE

VCC (OPR) = 2 V TO 6 V

■ PIN AND FUNCTION COMPATIBLE
