74LVXC4245 is a dual supply 8 bit configurable low voltage CMOS OCTAL BUS TRANSCEIVER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.
The 74LVXC4245 is a dual supply 8-bit configurable low voltage CMOS octal bus transceiver from STMicroelectronics. It is designed to interface a 5 V bus with a 3.3 V to 5 V bus in mixed 5 V/3.3 V systems, with data direction set by the DIR input and the G input used to isolate the buses.
The datasheet gives the pin connections and logic symbols, pin description, truth table, absolute maximum ratings, recommended operating conditions, DC and AC specifications, switching and capacitive characteristics, test circuits, waveforms, and package mechanical data for the SOP and TSSOP options.
| VCCA operating range | 4.5 V to 5.5 V |
|---|---|
| VCCB operating range | 2.7 V to 5.5 V |
| Maximum propagation delay | 6.5 ns at VCCA = 5.0 V, VCCB = 5.0 V |
| Supply current | 5 µA max per supply at 25 °C |
| Output drive current | 24 mA min |
| Operating temperature | -40 °C to 85 °C |

It is a dual supply 8-bit configurable low voltage CMOS octal bus transceiver.
The direction of data transmission is determined by the DIR input.
The G input can disable the device so the buses are effectively isolated.
The datasheet lists SOP 74LVXC4245MTR and TSSOP 74LVXC4245TTR.
