description  
The ’AHCT594 devices contain an 8-bit serial-in,  
parallel-out shift register that feeds an 8-bit D-type  
storage register. Separate clocks and direct  
overriding clear (SRCLR, RCLR) inputs are  
provided on both the shift and storage registers.  
NC – No internal connection  
A serial (Q ) output is provided for cascading  
H  
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 count pulse ahead of the storage register.  
The SN54AHCT594 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74AHCT594 is characterized for operation from –40°C to 85°C.
