Description

The SN74LVTH62240DGGR is an integrated circuit designed by Texas Instruments, belonging to the LVTH family of devices. It is a low-voltage, high-performance 16-bit bus transceiver with 3-state outputs, suitable for driving large capacitive loads. This device operates from a supply voltage range of 2.7V to 3.6V and is capable of interfacing with TTL levels, making it ideal for mixed-voltage system applications.
The SN74LVTH62240DGGR features two 8-bit sections with separate control inputs, allowing for independent operation. It includes output-enable (OE) and direction (DIR) inputs to control the flow of data. The outputs are in a high-impedance state when the OE input is high, enabling bus isolation.
The device is equipped with bus-hold circuitry to eliminate the need for external pull-up resistors on unused inputs. It also has an increased drive of up to ±24mA, providing enhanced performance for driving heavy loads. The device is packaged in a TSSOP (Thin Shrink Small Outline Package), ensuring a compact form factor suitable for space-constrained applications.
