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

■ OPERATING VOLTAGE RANGE:

VCC(OPR) = 2V to 3.6V (1.2V Data Retention)

■ PIN AND FUNCTION COMPATIBLE WITH

74 SERIES 373

■ IMPROVED LATCH-UP IMMUNITY

74LVX373属于集成电路（IC） > 锁存器。意法半导体（ST）集团制造生产的74LVX373锁存器锁存器是类似于触发器的基本数字存储设备，但是不同之处在于，在锁存使能（或类似命名）信号处于有效逻辑状态的任何时间，保持的逻辑状态都可以改变。“透明”锁存器还允许设备输出在锁存使能信号有效时反映输入的当前状态，而相反的是，状态仅在保持状态已固定时改变。
