It operates from a 4.75V to 5.25V supply rail, making it a 5V-only logic part — there is no 3.3V compatibility on the supply or the I/O. The two elements each handle four bits, giving an 8-bit bus width total. Output drive is asymmetric: 15mA source, 64mA sink, which is the spec that matters when you are terminating a backplane or driving a long trace on a test fixture. ## Active lifecycle, but a legacy form factor The through-hole DIP package, however, is a legacy footprint — most new designs have moved to surface-mount logic. If your BOM requires a DIP-20 socket and a 5V-only buffer, this part is a direct fit. For a surface-mount replacement, you would need to look at a different package variant within the 74FCT family or a functionally similar part like the SN74ABT2245DW, but that is a transceiver, not a buffer, and its pinout differs. ## 15mA source, 64mA sink — the drive asymmetry matters The 15mA source / 64mA sink current rating is the headline parametric for this buffer. The high sink current is what lets it drive terminated lines or high-capacitance loads on a 5V backplane. The source side is weaker, so if your load is primarily pull-up terminated to VCC, you may need to parallel two buffers or check the voltage drop at 15mA against your logic-high threshold. This asymmetry is typical of bipolar and BiCMOS logic families; it is not a flaw, but it is a constraint a designer new to 74FCT should budget for.","metaTitle":"CD74FCT244ATE 74FCT Buffer IC, 20-DIP, 5V, 3-State","metaDescription":"CD74FCT244ATE 74FCT buffer IC, non-inverting, 3-state outputs. 4.75V-5.25V supply, 15mA/64mA drive. 20-DIP through-hole package.","metaKeywords":null},"attributes":{"series":"74FCT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"74FCT","Package":"Tube","Logic Type":"Buffer, Non-Inverting","Output Type":"3-State","Mounting Type":"Through Hole","Package / Case":"20-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Number of Elements":"2","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"20-PDIP","Current - Output High, Low":"15mA, 64mA","Number of Bits per Element":"4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.15","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.15000","currency":"USD"},{"qty":10,"price":"$1.02600","currency":"USD"},{"qty":25,"price":"$0.97360","currency":"USD"},{"qty":100,"price":"$0.79970","currency":"USD"},{"qty":250,"price":"$0.74752","currency":"USD"},{"qty":500,"price":"$0.66060","currency":"USD"},{"qty":1000,"price":"$0.52152","currency":"USD"},{"qty":2500,"price":"$0.49200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/228ef0c051c705b3f448c9fde308da7a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can I use CD74FCT244ATE with 3.3V logic?","answer":"No. The supply voltage range is 4.75V to 5.25V.
