Product details

8-bit buffer with 3-state outputs in 20-SSOP

The Texas Instruments CY74FCT244TQCTG4 is an 8-bit buffer and line driver with non-inverting outputs and 3-state control, part of the 74FCT series. It contains two 4-bit elements per package, each with its own output enable, making it a direct fit for bus-oriented designs where the data path needs to be isolated or driven onto a shared bus. The output drive is rated 32 mA source and 64 mA sink — the asymmetric sink capability is typical for TTL-compatible bus interfaces where the load is primarily capacitive and the low-level noise margin benefits from the higher pull-down current.

Temperature grade and package fit

Surface-mount assembly with a standard 0.65 mm lead pitch. The narrow body width keeps the board footprint compact for dense digital sections where multiple bus transceivers sit side by side.

Frequently asked questions

What is the output drive capability of this buffer?

The CY74FCT244TQCTG4 sources 32 mA and sinks 64 mA per output. The asymmetric sink current is designed for TTL bus loads where the low-level noise margin benefits from higher pull-down drive.
