Product details

5V octal buffer — 32 mA source, 64 mA sink

The CY74FCT244DTSOCT from the 74FCT series is a non-inverting octal buffer with 3-state outputs, split into two 4-bit elements. Each output can source 32 mA and sink 64 mA, enough to drive a TTL bus or a bank of LEDs without external transistors.

Temperature grade — indoor only

It belongs in office equipment, bench instruments, or appliance control boards — not in a motor drive enclosure or under the hood. If the BOM calls for industrial or automotive temp, this one won't cut it.

Frequently asked questions

What is the closest functional equivalent for CY74FCT244DTSOCT?

The SN74LVTH16245ADGVR is a 3.3 V transceiver with 32 mA drive and 8-bit elements, but it runs on 2.7 V supply and has a different pinout (transceiver vs buffer). For a direct 5 V octal buffer replacement, stick with the 74FCT244 family in 20-SOIC.
