74FCT244ATSOG8

Buffers, Drivers, Receivers, Transceivers Overview

The IDT 74FCT244ATSOG8 is an octal buffer and line driver belonging to the FCT logic series. It features eight non-inverting input lines and eight corresponding output lines housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Electrical characteristics include a high-level output current capability of -15 mA and a low-level output current of 64 mA. Quiescent current is specified at 10 µA, with a maximum operating supply current of 5 mA. The component supports a functional temperature range from -40 °C to +85 °C.

• System clock distribution networks

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation as IDT or Renesas Electronics, as product lines were transferred. Confirm the specific suffix ATSOG8 corresponds to the SOIC-20 package variant. Ensure RoHS compliance status matches project requirements by checking the latest datasheet revision. Validate that the operating temperature range meets environmental constraints.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal, non-inverting buffer is required for 5V logic systems. The FCT series offers faster switching speeds compared to standard LS logic. Consider the 64 mA low-level sink capability for driving heavy capacitive loads. Verify pinout compatibility if replacing legacy devices from other manufacturers in the same form factor.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74FCT family of high-speed CMOS logic devices. It serves as a buffer/line driver, distinct from transceivers like the 74FCT2245 which support bidirectional traffic. The device is functionally similar to the 74FCT244CTSOG8 but may differ in packaging or specific electrical tolerances defined by the manufacturer's revisions.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The CY74FCT2244TSOC from Texas Instruments is listed as a similar alternative, though it is a dual 4-bit configuration rather than octal. Direct substitutes should be verified against the official datasheet for pin-to-pin compatibility and electrical parameter alignment.
