Frequently Asked Questions
What is the maximum operating frequency of the CD74ACT374EE4?
The CD74ACT374EE4 supports a maximum clock frequency of 110MHz at nominal supply voltage. This high-speed performance, enabled by ACT CMOS technology, makes it suitable for fast synchronous data capture and bus driving in digital logic designs requiring rapid register updates.
What package does the CD74ACT374EE4 use and how many pins does it have?
The CD74ACT374EE4 is housed in a 20-pin PDIP (Plastic Dual In-Line Package) with through-hole mounting, identified by the JESD-30 code R-PDIP-T20. The PDIP format is suitable for breadboard prototyping and socketed industrial applications where component replacement is needed.
How does the 3-state output enable work on the CD74ACT374EE4?
The CD74ACT374EE4 features an active-low output enable (OE) pin that controls all eight outputs simultaneously. When OE is LOW, the outputs drive the stored data values. When OE is HIGH, all outputs enter high-impedance (3-state) mode, effectively disconnecting the device from the bus to prevent signal conflicts with other drivers.
What supply voltage does the CD74ACT374EE4 require?
The CD74ACT374EE4 operates from a 4.5V to 5.5V supply voltage (nominally 5V), which is standard for the ACT CMOS logic family. Its TTL-compatible input thresholds (VIL ≤ 0.8V, VIH ≥ 2.0V) ensure direct interfacing with both TTL and CMOS 5V logic devices.
What is a common alternative or equivalent to the CD74ACT374EE4?
Compatible alternatives include the SN74ACT374 from Texas Instruments in various package options, the 74HCT374 (HCT family, lower speed), and the CD74HC374 (HC family, 2V–6V operation). The CD74ACT374EE4's ACT family designation indicates TTL-input thresholds, distinguishing it from HC variants which require CMOS-level inputs.
