The MM74HCT244MTCX from onsemi is a dual 4-bit non-inverting buffer with 3-state outputs. Operating from 4.5V to 5.5V, it is TTL-compatible, making it a drop-in replacement for legacy TTL buffers. It provides 7.2mA source and sink current, suitable for driving LEDs and logic signals. The 20-TSSOP package is compact for space-limited designs. This buffer is ideal for 5V systems, industrial controls, and automotive applications.
- TTL-Compatible Inputs: Directly interfaces with legacy TTL logic without extra components.
- Dual 4-Bit Channels: Provides 8 buffers in one package, saving board space.
- 3-State Outputs: Enables bus sharing and prevents signal contention.
- Wide 5V Supply Range: Compatible with standard 5V power rails.
