1 General description

The 74AVC16373 is a 16-bit D-type transparent latch featuring separate D-type inputs

for each latch and 3-state outputs for bus oriented applications. One latch enable (LE)

input and one output enable (OE) input are provided per 8-bit section. The 74AVC16373

consist of two sections of eight D-type transparent latches with 3-state true outputs.

The 74AVC16373 is designed to have an extremely fast propagation delay and a

minimum amount of power consumption.

To ensure the high-impedance output state during power-up or power-down, pin nOE

should be tied to VCC through a pull-up resistor (Live Insertion).

A dynamic controlled output (DCO) circuitry is implemented to support termination line

drive during transient (see Figure 5).

2 Features and benefits

• Wide supply voltage range from 1.2 V to 3.6 V

• Complies with JEDEC standards:

– JESD8-7 (1.2 V to 1.95 V)

– JESD8-5 (1.8 V to 2.7 V)

– JESD8-1A (2.7 V to 3.6 V)

• CMOS low power consumption

• Input/output tolerant up to 3.6 V

• Dynamic Controlled Output (DCO) circuit dynamically changes output impedance,

resulting in noise reduction without speed degradation

• Low inductance multiple VCC and GND pins to minimize noise and ground bounce

• Supports Live Insertion

74AVC16373属于集成电路（IC） > 锁存器。安世半导体(中国)有限公司制造生产的74AVC16373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。
