1 / 27 page SN74HCS594 8-Bit Shift Register With Schmitt-Trigger Inputs and Output Registers 1 Features • Wide operating voltage range: 2 V to 6 V • Schmitt-trigger inputs allow for slow or noisy input signals • Low power consumption – Typical ICC of 100 nA – Typical input leakage current of ±100 nA • ±7.8-mA output drive at 6 V • Extended ambient temperature range: –40°C to +125°C, TA 2 Applications • Output expansion • LED matrix control • 7-segment display control • 8-bit data storage 3 Description The SN74HCS594 device contains an 8-bit, serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. All inputs include Schmitttriggers, eliminating any erroneous data outputs due to slow- edged or noisy input signals. The storage register has parallel outputs. Separate clocks and direct overriding clear (SRCLR, RCLR) inputs are provided for both the shift and storage register. A serial output (QH') is provided for cascading. Both the shift register (SRCLK) and storage register (RCLK) clocks are positive edge triggered. If both clocks are connected together, the shift register is one count pulse ahead of the storage register.
