Frequently Asked Questions
How fast can CD74ACT299M96 operate, and does it fit designs running at 3.3 V logic levels?
CD74ACT299M96 supports a maximum clock frequency of 90 MHz, which comfortably fits most high-speed digital bus and FIFO applications. The ACT family uses TTL-compatible inputs accepting signals from 0 V to 5 V, and VCC can be 4.5 V to 5.5 V for standard 5 V system integration.
What differentiates CD74ACT299M96 from standard 74HC or 74LS shift registers in a bus buffer design?
Unlike 74HC or 74LS parts, the ACT family combines CMOS low-power consumption with TTL input thresholds, allowing CD74ACT299M96 to interface directly with both CMOS and TTL logic at speeds up to 90 MHz. Common I/O pins reduce trace count, and the 50 pF load tolerance supports longer PCB traces without additional buffering.
What is the pin count and package body size of CD74ACT299M96 for PCB footprint planning?
CD74ACT299M96 is housed in a 20-pin SOIC package (JESD-30 code R-PDSO-G20), which has a standard 1.27 mm pin pitch and a body width of approximately 7.5 mm. This compact footprint is compatible with automated pick-and-place and reflow processes used in high-volume board production.
Can CD74ACT299M96 be daisy-chained for 16-bit or wider shift-register configurations?
Yes. CD74ACT299M96 provides totem-pole serial shift-right and shift-left outputs specifically for cascading multiple 8-bit stages. Two devices can extend the register to 16 bits, and the asynchronous reset line on each device allows all stages to be cleared simultaneously during power-up with a single control signal.
What compliance status does CD74ACT299M96 carry for use in regulated-market designs?
CD74ACT299M96 (M96 tape-and-reel suffix) is manufactured as a Pb-free, RoHS-compliant component under JESD-609 code e4. This makes it suitable for designs subject to EU RoHS Directive requirements, reducing material declaration effort for industrial and commercial electronics applications.
