74AHC595S16-13

Shift Registers Overview

The 74AHC595S16-13 is an advanced high-speed CMOS 8-bit shift register with an 8-bit output register, manufactured by Diodes Incorporated. It accepts serial data via the DS input on positive transitions of the shift register clock (STCP). An active-low master reset (MR) clears all shift register values independently of clocks. Data transfers to the storage register on rising pulses of the storage register clock (SHCP). The device features three-state outputs controlled by an active-low output enable (OE). It operates within a supply voltage range of 2.0 V to 5.5 V and supports an operating temperature from -40°C to +125°C.

Shift Registers Procurement Notes

Verify the specific package code S16 corresponds to the SO-16 footprint required for your PCB layout. Confirm that the -13 suffix indicates the standard 2500-unit tape and reel packaging format. Ensure the component meets RoHS compliance requirements for your manufacturing process. Check datasheet revision DS35486 Rev. 3 - 2 for any updates to electrical characteristics or ordering information before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when a high-speed CMOS shift register with wide voltage compatibility is needed. The AHC series offers balanced propagation delays suitable for general digital applications. Verify that the 8mA sink/source capability at 4.5V meets load requirements. Consider the SO-16 package dimensions against available board space. Ensure input voltage levels remain within the 0 to 5.5V range to prevent damage.

Shift Registers Part Context

This part belongs to the 74AHC595 family of 8-bit shift registers produced by Diodes Incorporated. It is designed as an advanced high-speed CMOS device compatible with standard logic interfaces. The S16 designation identifies the surface-mount SO-16 package variant. It serves as a digital logic component for data shifting and latching operations in electronic systems.

Shift Registers Replacement Considerations

Direct substitutes include other manufacturers' 74AHC595 variants in SO-16 packages. Verify pinout compatibility and electrical parameters such as propagation delay and supply voltage range. Ensure replacement parts maintain the same logic family characteristics and package dimensions for seamless integration.

Shift Registers FAQ

How does the master reset function operate?

The master reset (MR) function sets all shift register values to zero when asserted low. This operation is independent of all clock signals.

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

Data shifts into the register on the positive transition of STCP. Data moves to the storage register on the rising pulse of SHCP. If both clocks are connected, the shift register remains one cycle ahead of the storage register.

What happens when the output enable pin is high?

When the output enable (OE) pin is asserted high, all Q outputs enter a high-impedance state, effectively disconnecting them from the circuit.
