SN74AHCT374N集成电路（IC）的触发器规格书PDF中文资料

SN74AHCT374N属于集成电路（IC）的触发器。由德州仪器制造生产的SN74AHCT374N触发器触发器是能够存储单个逻辑状态或信息“位”的基本数字存储器件。这些器件至少有两个输入；一个或多个用于传递要存储的数据，另一个用于指示存储该数据的时间点。不同的触发器类型，例如 D（延迟）、SR（置位复位）和 JK，对提供给其输入的信号有不同的响应，可用于实现不同的逻辑功能。这些器件与锁存器的不同之处在于它们是边缘敏感器件，其保持的逻辑状态仅在接收到有效时钟信号时才会改变。

1 Features

• Operating range 4.5V to 5.5V VCC

• TTL-Compatible inputs

• Low delay, 10.5ns (5V VCC at CL = 15pF)

• Supports 75MHz

• Latch-up performance exceeds 250mA

per JESD 17

• On products compliant to MIL-PRF-38535, all

parameters are tested unless otherwise noted. On

all other products, production processing does not

necessarily include testing of all parameters.

2 Applications

• Parallel data synchronization

• Parallel data storage

• Shift register

• Pattern generators

3 Description

The SNx4AHCT374 contains eight D-type flip-flops.

All channels share a rising edge triggered clock (CLK)

input and active low output enable (OE) input. This

device has a flow-through pinout which allows for

easier bus routing.
