What are the key features of CD74AC164M?
- 8-bit serial-in parallel-out operation with dual gated serial inputs for data masking without additional logic
- Wide supply range of 1.5 V to 5.5 V, compatible with both 3.3 V and 5 V system rails
- AC CMOS logic family with 24 mA output current capacity and 50 pF load rating for medium-fanout bus driving
What is CD74AC164M used for?
The CD74AC164M is well-suited for expanding microcontroller I/O by converting a serial SPI or UART data stream into 8 parallel output lines for LED arrays, relay banks, or display segments. Its wide 1.5 V to 5.5 V supply range makes it compatible with both 3.3 V microcontrollers and legacy 5 V logic in mixed-voltage embedded designs. It also serves as a pipeline register or bit-serial accumulator in digital signal processing chains requiring 8-bit parallel output latching.

Frequently Asked Questions
How fast can CD74AC164M shift data and at what supply voltage does it achieve its best speed?
The CD74AC164M in the AC logic family achieves typical propagation delays below 10 ns at a 5 V supply with a 50 pF load, enabling clock frequencies above 50 MHz for serial-to-parallel conversion. At lower supply voltages such as 3.3 V, propagation delay increases but the device remains functional across the full 1.5 V to 5.5 V range, making it usable in low-power embedded designs even at clock rates of 10 MHz to 20 MHz.
In an LED matrix driver design, how does the dual serial-input gating of CD74AC164M simplify control logic?
The CD74AC164M has two gated serial data inputs (A and B) that are ANDed internally, so holding one input low blanks the shift register without requiring an external AND gate or additional I/O pin on the microcontroller. In a 64-LED matrix driven by 8 daisy-chained CD74AC164M devices, this feature reduces MCU pin count by 8 and eliminates 8 discrete AND gates compared to shift registers with a single ungated data input.
When migrating from a 5 V system to a 3.3 V rail, does CD74AC164M require level shifters on its clock and data inputs?
No, the CD74AC164M's AC CMOS inputs are compatible with 3.3 V logic levels when the device is powered at 3.3 V, as the input high threshold is approximately 70% of VCC (about 2.3 V at 3.3 V supply) and 3.3 V CMOS outputs typically drive 3.0 V to 3.3 V. This eliminates the need for level shifters in most 3.3 V-to-3.3 V system migrations, simplifying the transition from 5 V legacy boards at no extra component cost.
