74AHC595T16-13

Shift Registers Overview

The 74AHC595T16-13 is an advanced high-speed CMOS device featuring an 8-bit shift register and an 8-bit output register. It accepts serial data on the DS input during positive transitions of the STCP clock. The MR pin clears the shift register when low, independent of clocks. Data transfers to the storage register via SHCP rising pulses. With OE asserted low, 3-state outputs Q0-Q7 become active. The device operates within a supply voltage range of 2.0 V to 5.5 V.

Shift Registers FAQ

How does the Master Reset (MR) function operate?

When the MR input is asserted low, it sets all shift register values to zero. This operation is independent of all clock signals.

What is the relationship between the shift register and output register clocks?

Data from the input serial shift register is placed into the output register with a rising pulse on the storage register clock (SHCP). If both clocks are connected together, the input shift register remains one clock cycle ahead of the output register.
