SN74LVC8T245DGVR – TEXAS INSTRUMENTS

The SN74LVC8T245DGVR is an 8-bit bidirectional transceiver with 3-state outputs, optimized for low-power applications within the 1.65V to 5.5V voltage range. This device operates using low-voltage CMOS (LVCMOS) technology, offering significantly reduced power consumption compared to its TTL counterparts. Packaged in a space-saving 20-pin TSSOP (Thin Shrink Small Outline Package), it features independent direction control (DIR) and output enable (OE) pins, allowing for flexible data flow management. Internal circuitry includes Schmitt-trigger inputs for enhanced noise immunity, crucial in noisy environments._x000D_

The SN74LVC8T245DGVR excels in applications requiring high-speed, bidirectional data transmission with low power dissipation, such as interfacing microcontrollers with peripherals, memory expansion, or implementing data buses in portable devices. Its 3-state output capability enables easy bus sharing and simplifies system design. The device’s wide operating voltage range ensures compatibility across various power supply designs, while its low propagation delays (typically under 7ns) contribute to faster system clock speeds. The use of LVCMOS technology provides advantages in reduced power consumption and improved noise immunity compared to older technologies like TTL or HCMOS, making it a superior choice for battery-powered or space-constrained designs.
