8位并联负载移位寄存器 8-BIT PARALLEL-LOAD SHIFT REGISTERS
description/ordering information
The ’HC165 devices are 8-bit parallel-load shift registers that, when clocked, shift the data toward a serial QH output. Parallel-in access to each stage is provided by eight individual direct data A−H inputs that are enabled by a low level at the shift/load SH/LD input. The ’HC165 devices also feature a clock-inhibit CLK INH function and a complementary serial QH output.
