Frequently Asked Questions
What is the SN74BCT374DW and what does it do?
The SN74BCT374DW is an octal (8-bit) D-type flip-flop with 3-state outputs from Texas Instruments, part of the BCT (BiCMOS) logic family. It captures 8 bits of data on the rising clock edge and holds it until the next clock cycle, with 3-state outputs that can be disabled to share a data bus with other devices.
What are the key electrical specifications of the SN74BCT374DW?
The SN74BCT374DW operates from a 5V supply voltage and features TTL-compatible input thresholds. It offers propagation delays in the range of 5–8 ns, output drive capability of ±32 mA, and is rated for operation over the industrial temperature range of -40°C to +85°C.
What package does the SN74BCT374DW come in?
The SN74BCT374DW is housed in a SOIC-20 (DW) wide-body surface-mount package with 20 pins and 1.27 mm pitch, making it suitable for automated PCB assembly. Texas Instruments also offers this device in other package options such as PDIP-20.
What are typical applications for the SN74BCT374DW?
Typical applications include data bus buffering and isolation in microprocessor systems, address latching, I/O port expansion, pipeline registers, and backplane bus interfaces. The 3-state outputs allow multiple SN74BCT374DW devices to share a common 8-bit data bus without signal contention.
What are common alternatives or replacements for the SN74BCT374DW?
Compatible alternatives include the SN74ACT374 (ACT logic, faster and lower power), SN74AHCT374 (AHCT family, 3.3V/5V compatible), and SN74LS374 (LS-TTL, lower speed). The 74FCT374 from other manufacturers is also a functional equivalent. Selection depends on speed, power, and voltage requirements.
