Hex D Flip−Flop with Common Clock and Reset

High−Performance Silicon−Gate CMOS

The MC74HC174A is identical in pinout to the LS174. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.

This device consists of six D flip−flops with common Clock and Reset inputs. Each flip−flop is loaded with a low−to−high transition of the Clock input. Reset is asynchronous and active−low.

Features

• Output Drive Capability: 10 LSTTL Loads

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 2.0 to 6.0 V

• Low Input Current: 1.0 A

• In Compliance with the Requirements Defined by JEDEC Standard No. 7A

• Chip Complexity: 162 FETs or 40.5 Equivalent Gates

• Pb−Free Packages are Available*

MC74HC174ADR2G属于集成电路（IC） > 触发器。安森美半导体公司制造生产的MC74HC174ADR2G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。
