SN74HC595数据手册集成电路（IC）的移位寄存器规格书PDF

描述 Description

The SNx4HC595 devices contain an 8-bit, serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The storage register has parallel 3-state outputs. Separate clocks are provided for both the shift and storage register. The shift register has a direct overriding clear (SRCLR) input, serial (SER) input, and serial outputs for cascading. When the output-enable (OE) input is high, the outputs are in the high-impedance state.

特性 Features

• 8-bit serial-in, parallel-out shift
• Wide operating voltage range of 2 V to 6 V
• High-current 3-state outputs can drive up to 15 LSTTL loads
• Low power consumption: 80-µA (maximum) ICC
• tpd = 13 ns (typical)
• ±6-mA output drive at 5 V
• Low input current: 1 µA (maximum)
• Shift register has direct clear
• 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.
