Product details

What this buffer does — the 74FCT3244AQG8

The Renesas 74FCT3244AQG8 is a dual 4-bit non-inverting buffer with 3-state outputs, part of the 74FCT logic family. It operates from a 2.7V to 3.6V supply, making it a drop-in fit for 3.3V and 2.5V bus environments. Each of the two elements handles four bits, giving you eight buffer channels in one 20-pin QSOP package. The 3-state outputs let you isolate the buffer from the bus when the output-enable control is deasserted, which is the standard approach for shared data lines in memory interfaces, peripheral buses, or backplane signaling.

The output drive is rated at 8mA source and 24mA sink.

There is no NRND or EOL flag on this part, so it is safe to design into new BOMs without near-term obsolescence risk.

Frequently asked questions

What is the closest functional equivalent to 74FCT3244AQG8?

The 74FCT16245ATPAG8 is a 16-bit transceiver (8 bits per element, two elements) from the same 74FCT series, but it is a transceiver with bidirectional data flow, not a buffer. For a pure buffer function, the 74FCT3244AQG8 is the correct part. The 74LVCH32245ABFG is a 32-bit transceiver from the 74LVCH series operating at 2.7V, but it is also a transceiver, not a buffer.
