Frequently Asked Questions

What is the maximum operating frequency of the SN74ABT374APWG4?

The SN74ABT374APWG4 supports a maximum clock frequency of 150MHz (150,000,000 Hz) at nominal supply voltage. This high-speed performance is enabled by the ABT (Advanced BiCMOS Technology) logic family, which offers fast propagation delays and strong drive capability, making the device suitable for demanding bus interface and data path applications in high-speed digital systems.

What output drive capability does the SN74ABT374APWG4 provide?

The SN74ABT374APWG4 provides a maximum output low current (IOL) of 64mA (0.064A), delivering strong sink drive capability for driving bus loads in 3.3V and 5V systems. The 3-state outputs can be disabled using the active-low output enable pin, allowing multiple devices to share a common bus without signal contention or backdriving issues.

What package does the SN74ABT374APWG4 use?

The SN74ABT374APWG4 is housed in a 20-pin TSSOP (Thin Shrink Small Outline Package) surface-mount package with JEDEC code R-PDSO-G20. This package offers a compact footprint with 0.65mm lead pitch, making it suitable for high-density PCB layouts. The device is also lead-free (JESD-609 code e4), meeting RoHS environmental compliance requirements.

How does the 3-state output feature work on the SN74ABT374APWG4?

The SN74ABT374APWG4 includes an active-low output enable (OE) control that places all eight outputs into a high-impedance state when asserted. This 3-state capability allows multiple flip-flop devices to share a common data bus, with only one device driving the bus at a time. The control type is enable-low, meaning the outputs are active when OE is logic low and tri-stated when OE is logic high.
