74V1G77CTR集成电路（IC）的锁存器规格书PDF中文资料

74V1G77CTR属于集成电路（IC）的锁存器。由意法半导体集团制造生产的74V1G77CTR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。

DESCRIPTION

The 74V1G77 is an advanced high-speed CMOS SINGLE D-TYPE LATCH fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is designed to operate from 2V to 5.5V, making this device ideal for portable applications.

■ HIGH SPEED: tPD = 4.4ns (TYP.) at VCC = 5V

■ LOW POWER DISSIPATION:

ICC = 1µA(MAX.) at TA=25°C

■ HIGH NOISE IMMUNITY:

VNIH = VNIL = 28 VCC (MIN.)

■ POWER DOWN PROTECTION ON INPUTS

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 8mA (MIN) at VCC = 4.5V

■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL

■ OPERATING VOLTAGE RANGE:

VCC(OPR) = 2V to 5.5V

■ IMPROVED LATCH-UP IMMUNITY
