74LVQ573T集成电路（IC）的锁存器规格书PDF中文资料

74LVQ573T属于集成电路（IC）的锁存器。由意法半导体集团制造生产的74LVQ573T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 LVQ573 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 and low noise 3.3V applications.

It has better speed performance at 3.3V than 5V LSTTL family combined with the true CMOS low power consumption.

All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

■ HIGH SPEED: tPD = 5 ns (TYP.) at VCC = 3.3V

■ COMPATIBLEWITH TTL OUTPUTS

■ LOW POWER DISSIPATION:

ICC =4 µA (MAX.) at TA = 25 °C

■ LOW NOISE:

VOLP = 0.5 V (TYP.) at VCC = 3.3V

■ 75Ω TRANSMISSIONLINE DRIVING CAPABILITY

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 24 mA (MIN)

■ PCI BUS LEVELSGUARANTEED AT 24mA

■ BALANCEDPROPAGATIONDELAYS: tPLH ≅ tPHL

■ OPERATING VOLTAGERANGE:

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

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 573

■ IMPROVED LATCH-UP IMMUNITY
