SN74AHC594-Q1数据手册TI中文资料规格书

描述 Description

The SN74AHC594-Q1 is an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. Separate clocks (RCLK, SRCLK) and direct overriding clear (RCLR, SRCLR) inputs are provided on both the shift and storage registers. A serial (QH’) output is provided for cascading purposes.

Both the shift register (SRCLK) and storage register (RCLK) clocks are positive edge triggered. If both clocks are connected together, the shift register always is one clock pulse ahead of the storage register.
