What are the key features of CD74AC573M96E4?
- Octal 8-bit transparent latch with 3-state outputs for high-density bus interface in 2 V to 6 V systems
- AC CMOS logic family delivering fast propagation delays with low static power consumption across the full 2 V to 6 V supply range
- RoHS-compliant JESD-609 e4 lead-free 20-pin SOIC-20 package rated to 50 pF load capacitance for reliable high-speed bus driving
What is CD74AC573M96E4 used for?
The CD74AC573M96E4 is used as an address or data bus latch between microprocessors and memory or peripheral devices in embedded systems operating from 2 V to 6 V supply rails. Its transparent latch mode captures 8 bits of data when the latch-enable pin is asserted, then holds the captured state when LE goes LOW, making it ideal for demultiplexing multiplexed address/data buses. The 3-state outputs allow multiple latch devices to share the same 8-bit bus without signal contention in board-level memory expansion and I/O expansion designs.

Frequently Asked Questions
What supply voltage range and load capacitance does CD74AC573M96E4 support?
The CD74AC573M96E4 operates across a supply voltage range of 2 V to 6 V, covering both 3.3 V and 5 V logic systems in a single device. Its outputs are rated to drive a 50 pF load capacitance, which accommodates typical PCB trace and component input capacitances found in standard 8-bit bus interface designs without requiring external line-matching components.
How does the transparent latch function of CD74AC573M96E4 help demultiplex a shared address/data bus?
When the latch-enable (LE) input is HIGH, the CD74AC573M96E4 transparently passes all 8 input signals to its outputs in real time. When LE goes LOW, the device latches and holds the last input state, effectively storing 8 bits of address or data while the bus transitions to the next cycle. This behavior is essential for processors with multiplexed 8-bit address/data buses, since the latch captures the address phase and retains it for the full memory read or write cycle, typically lasting several tens of nanoseconds.
What are the 3-state output benefits of CD74AC573M96E4 in a multi-master bus design?
The CD74AC573M96E4 includes an active-LOW output-enable (OE) pin that places all 8 outputs into a high-impedance 3-state condition when de-asserted. This lets multiple CD74AC573 devices share the same 8 output lines without bus contention, which is critical in memory bank switching or multi-source data bus architectures. Each device can be individually selected by its OE pin, allowing a 2-to-8 or wider bus expansion with only standard logic control signals.
When should CD74AC573M96E4 be chosen over CD74HCT573 for a mixed 3.3 V / 5 V board?
CD74AC573M96E4 from the AC CMOS family accepts inputs from 2 V to 6 V and has TTL-compatible input thresholds, making it tolerant of 3.3 V drivers on a 5 V-powered latch and vice versa. In contrast, CD74HCT573 requires VCC at 5 V and has TTL input thresholds only at that voltage. For boards mixing 3.3 V microcontrollers with 5 V peripheral buses, the AC573 provides broader operating margin with propagation delays typically under 10 ns at 5 V, 50 pF load.
