Low-Voltage CMOS Octal Transparent Latch

With 5 V−Tolerant Inputs and Outputs (3−State, Non−Inverting)

The 74LVC573A is a high performance, non−inverting octal transparent latch operating from a 1.2 to 3.6 V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5 V allows 74LVC573A inputs to be safely driven from 5 V devices.

Features

• Designed for 1.2 to 3.6 V VCC Operation

• 5 V Tolerant − Interface Capability With 5 V TTL Logic

• Supports Live Insertion and Withdrawal

• IOFF Specification Guarantees High Impedance When VCC = 0 V

• 24 mA Output Sink and Source Capability

• Near Zero Static Supply Current in all Three Logic States (10 A) Substantially Reduces System Power Requirements

• ESD Performance:

♦ Human Body Model >2000 V

♦ Machine Model >200 V

• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant

74LVC573A属于集成电路（IC） > 锁存器。安森美半导体公司制造生产的74LVC573A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。
