描述 Description

The HEF4014B-Q100 is a fully synchronous edge-triggered 8-bit static shift register with eight synchronous parallel inputs (D0 to D7). It has a synchronous serial data input (DS), a synchronous parallel enable input (PE) and a LOW-to-HIGH edge-triggered clock input (CP). It also has buffered parallel outputs from the last three stages (Q5 to Q7).
Operation is synchronous and the device is edge-triggered on the LOW-to-HIGH transition of CP. Each register stage is of a D-type master-slave flip-flop type. When PE is HIGH, data is loaded into the register from D0 to D7 on the LOW-to-HIGH transition of CP. When PE is LOW, data is shifted to the first position from DS. All the data in the register is shifted one position to the right on the LOW-to-HIGH transition of CP. The Schmitt trigger action of the clock input makes the HEF4014B-Q100 highly tolerant of slower clock rise and fall times.
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 3) and is suitable for use in automotive applications.
