并联负载8位移位寄存器 PARALLEL-LOAD-8-BIT SHIFT REGISTERS

description

The ’165 and ’LS165A are 8-bit serial shift registers that shift the data in the direction of QA toward QH when clocked. Parallel-in access to each stage is made available by eight individual,

direct data inputs that are enabled by a low level at the shift/load SH/LD input. These registers

also feature gated clock CLK inputs and complementary outputs from the eighth bit. All inputs are diode-clamped to minimize transmission-line effects, thereby simplifying system design.
