Key Features
- 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs.
- Separate clocks for shift and storage registers.
- Serial input (DS) and serial output (Q7S) for cascading.
- Asynchronous reset MR input; a LOW on MR resets the shift register.
- Data shifted on LOW-to-HIGH transitions of the SHCP input and transferred to the storage register on LOW-to-HIGH transition of the STCP input.
- Output enable input (OE) controls the output state; HIGH on OE causes outputs to assume a high-impedance OFF-state.
- Inputs include clamp diodes for interfacing with voltages in excess of VCC.
- Complies with JEDEC standard no. 7A.
- Multiple package options, including DHVQFN with Side-Wettable Flanks for Automated Optical Inspection (AOI) of solder joints.

Q & A
- What is the primary function of the 74HCT595D-Q100?
The primary function is to act as an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs.
- What are the operating temperature ranges for the 74HCT595D-Q100?
The device operates over a temperature range of -40 °C to +125 °C.
- What is the supply voltage range for this component?
The supply voltage range is 4.5 V to 5.5 V.
- How does the output enable input (OE) affect the outputs?
A HIGH on the OE input causes the outputs to assume a high-impedance OFF-state, while a LOW on OE allows the data in the storage register to appear at the output.
- What type of input levels does the 74HCT595D-Q100 support?
The device supports TTL input levels.
- What is the typical shift out frequency of the 74HCT595D-Q100?
The typical shift out frequency is 100 MHz.
- Does the 74HCT595D-Q100 have ESD protection?
Yes, it has ESD protection: HBM exceeds 2000 V and CDM exceeds 1000 V.
- What package options are available for the 74HCT595D-Q100?
Available package options include 16-SOIC and DHVQFN with Side-Wettable Flanks.
- How does the asynchronous reset MR input work?
A LOW on the MR input resets the shift register.
- Can the 74HCT595D-Q100 be used in cascaded configurations?
Yes, it can be used in cascaded configurations due to its serial input (DS) and serial output (Q7S).
