Frequently Asked Questions
What is the SN74LV244ATRGYRG4 and what does it do?
The SN74LV244ATRGYRG4 is an octal (8-channel) buffer and line driver with 3-state outputs from Texas Instruments. It buffers and drives digital signals on data/address buses, supporting supply voltages from 1.65V to 5.5V. The 3-state output feature allows multiple drivers to share a common bus without contention. The TRGYRG4 suffix denotes TSSOP-20 package in tape-and-reel, AEC-Q100 automotive grade.
What are the key electrical specifications of SN74LV244ATRGYRG4?
Key specs: supply voltage VCC = 1.65V to 5.5V; output drive current IOH/IOL = ±24mA (at 3.3V); propagation delay tpd ≈ 5.5ns at 3.3V; input voltage compatibility covers 1.8V, 2.5V, 3.3V and 5V logic; operating temperature -40°C to +85°C; 20-pin TSSOP package with 0.65mm pitch.
What package does SN74LV244ATRGYRG4 come in, and what is the pin count?
SN74LV244ATRGYRG4 comes in a TSSOP-20 (Thin Shrink Small Outline Package) with 20 pins and 0.65mm pitch. The TRGYRG4 suffix indicates tape-and-reel packaging for automated SMT assembly. Pin 1 and 19 are output-enable controls (OE1, OE2); pins 2–9 and 12–19 are inputs/outputs for the 8 buffer channels.
What are the alternatives or equivalents to SN74LV244ATRGYRG4?
Compatible alternatives include: 74LVC244A (Nexperia, ON Semi, Diodes Inc.) — same function with slightly different drive specs; SN74LVC244A from TI — same function at 1.65V–3.6V; 74ALVCH244 for higher-speed applications; and 74HCT244 for 5V-only systems. Always verify supply voltage range and drive current before substituting.
How do I order SN74LV244ATRGYRG4 and what is the minimum order quantity?
SN74LV244ATRGYRG4 is available with a minimum order quantity (MOQ) of 1,000 pieces. Pricing starts at $0.285 per unit at 1,000 pcs, $0.256 at 3,000 pcs, and $0.235 at 6,000 pcs. Submit an RFQ through FindMyChip for a formal quotation with lead time and delivery options.
