SN74LVC4245APWR Description

Short technical summary and product information.

The Texas Instruments SN74LVC4245APWR is an 8-bit (octal) noninverting bus transceiver designed for voltage translation between 3.3V and 5V environments. It features two separate supply rails, VCCB set at 3.3V and VCCA set at 5V, enabling seamless bidirectional translation.

 

This transceiver operates at a maximum data rate of 200 Mbps with a propagation delay of 6.7 ns. It supports applications such as GPIO, JTAG, SPI, and UART. Key electrical features include a push-pull topology, high drive strength of 24mA at 3V, and an output enable feature. The device operates within a temperature range of -40°C to 85°C.

 

Packaged in a 24-TSSOP, the SN74LVC4245APWR is designed for surface mounting. It includes robust features like glitch-free power supply sequencing, VCC isolation, and VCC disconnect. If VCC drops below 100mV or is left floating, all I/O outputs are disabled and become high impedance. Control inputs VIH/VIL levels are referenced to VCCA voltage. Latch-up performance exceeds 250mA per JESD 17, and ESD protection exceeds 2000V (Human-Body Model) and 1000V (Charged-Device Model).

 

The SN74LVC4245APWR is compatible with the SN74LVC4245. Its Ioff feature supports partial-power-down node operation.
