Q & A
- What is the primary function of the 74AHCT595D,112?
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 is the supply voltage range for this IC?
The supply voltage range is from 2.0 V to 5.5 V. - What type of input levels does the 74AHCT595D,112 support?
The 74AHCT595D,112 supports TTL compatible input levels. - Does the 74AHCT595D,112 have overvoltage tolerant inputs?
- What is the operating temperature range for this IC?
The operating temperature range is from -40 °C to +85 °C and from -40 °C to +125 °C.- How does the output enable (OE) input affect the device?
A LOW on the OE input causes the outputs to be active, while a HIGH on OE causes the outputs to assume a high-impedance OFF-state.- Can the 74AHCT595D,112 be used in mixed voltage environments?
- What type of ESD protection does the 74AHCT595D,112 have?
The device has HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V and CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V ESD protection.- What is the significance of the separate clocks for the shift and storage registers?
The separate clocks allow for flexible data shifting and storage, enabling the shift register to always be one clock pulse ahead of the storage register if both clocks are connected together.- What are some common applications for the 74AHCT595D,112?
