SN74LVC4245APWR non-inverting bus transceiver
The SN74LVC4245APWR is an 8-bit, dual-supply, non-inverting bus transceiver from Texas Instruments that performs bidirectional level-shifting between two voltage domains. Packaged in a 24-pin TSSOP (PW) body with 0.65 mm pitch, it is designed for asynchronous communication between a 3.3 V (or lower) CMOS bus and a legacy 5 V TTL/CMOS bus. By providing true 3-State outputs and separate VCCA (1.65 V–5.5 V) and VCCB (1.65 V–5.5 V) rails, the device eliminates the need for external components and offers 24 mA drive capability while maintaining sub-3 ns propagation delay and sub-1 µA standby current .
SN74LVC4245APWR bus transceiver Applications
● Level-shifted data transfer between 1.8 V FPGAs and 5 V peripheral buses in industrial PLCs
● PCMCIA/Compact-Flash sockets in notebook computers requiring 3.3 V ↔ 5 V translation
● SPI or UART links in test equipment where DIR pin allows on-the-fly reversal of data direction
● Hot-swappable line cards in telecom racks thanks to Ioff and 3-State isolation
● GPIO expansion on battery-powered instruments, benefiting from <1 µA power-down current
Alternative level shifter/transceiver chips
● SN74LVC4245ADWR – SOIC-24 version from TI for wider pad pitch and manual soldering
● SN74LVC4245APW – TSSOP-24 variant without tape-and-reel, same electricals
● 74LVC4245A (Nexperia) – identical pin-out, 200 Mbps, industrial -40 °C to +125 °C option
● TXB0108 (TI) – auto-direction 8-bit level shifter when DIR control is undesirable
● FXL4TD245 (onsemi) – dual-supply 4-bit transceiver for narrower bus widths and smaller QFN footprint
