74LVX373集成電路（IC）的鎖存器規(guī)格書PDF中文資料

74LVX373屬于集成電路（IC）的鎖存器。由意法半導(dǎo)體集團制造生產(chǎn)的74LVX373鎖存器鎖存器是類似于觸發(fā)器的基本數(shù)字存儲設(shè)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(shè)備輸出在鎖存使能信號有效時反映輸入的當(dāng)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 74LVX373 is a low voltage CMOS OCTAL D-TYPE LATCH with 3 STATE OUTPUT NON INVERTING fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power, battery operated and low noise 3.3V applications.

■ HIGH SPEED:

tPD=5.8ns (TYP.) at VCC = 3.3V

■ 5V TOLERANT INPUTS

■ POWER-DOWN PROTECTION ON INPUTS

■ INPUT VOLTAGE LEVEL:

VIL = 0.8V, VIH = 2V at VCC =3V

■ LOW POWER DISSIPATION:

ICC = 4 μA (MAX.) at TA=25°C

■ LOW NOISE:

VOLP = 0.3V (TYP.) at VCC =3.3V

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 4 mA (MIN) at VCC =3V

■ BALANCED PROPAGATION DELAYS:

tPLH ? tPHL
