What are the key features of CD74ACT164M?
- 8-stage serial-in parallel-out shift register clocked up to 70 MHz for high-speed SPI data expansion
- ACT-family TTL-compatible inputs with 24 mA IOL output current supporting direct LED or bus drive
- Compact 14-pin SOIC surface-mount package with 50 pF rated load for dense PCB layouts
What is CD74ACT164M used for?
CD74ACT164M is used to expand microcontroller output ports by converting a 2-wire serial SPI stream into 8 parallel outputs for driving LED arrays, relay banks, or segment displays. Its 70 MHz maximum clock frequency makes it suitable for high-speed data serialization in digital communication boards. The ACT family's TTL-compatible inputs ensure reliable interfacing with 5 V logic systems in industrial control equipment.

Frequently Asked Questions
How fast can CD74ACT164M shift data, and what determines the maximum clock frequency?
CD74ACT164M supports a maximum clock frequency of 70 MHz at 5 V supply with a 50 pF load capacitance. The ACT-family's fast propagation time and TTL-threshold inputs allow reliable clocking in high-speed serial-to-parallel expansion applications, making it suitable for SPI-based LED matrix and relay control schemes running well above typical 10 MHz SPI rates.
Which output port expansion designs can benefit from CD74ACT164M's 8-bit parallel output?
CD74ACT164M is ideal for microcontroller port expansion where GPIO is scarce. A single 2-wire SPI interface (data + clock) drives all 8 parallel outputs simultaneously after shifting in one byte, controlling 8 LEDs, 8 relay channels, or 8 display segments. Cascading two CD74ACT164M ICs gives 16 parallel outputs from the same 2-wire interface.
What package does CD74ACT164M use, and how does it fit on standard PCB footprints?
CD74ACT164M uses a 14-pin SOIC package with 1.27 mm pin pitch and a 3.9 mm body width. This standard narrow SOIC-14 footprint is compatible with JEDEC MS-012 land patterns found in common PCB CAD libraries, simplifying board layout and enabling automated pick-and-place assembly in volume production.
When is CD74ACT164M preferred over CD74HC164 in a 5 V TTL-interfaced design?
CD74ACT164M is preferred when the driving source uses TTL output levels (VOH around 2.4 V) rather than CMOS levels (VOH near VCC). The ACT family's VIH threshold of 2 V accepts TTL HIGH levels reliably, while the HC164's 3.5 V VIH minimum may fail with TTL sources at 5 V. Both parts are functionally identical 8-bit SIPO shift registers with the same 14-pin SOIC pinout.
