The SN74LVC16245AGRDR from Texas Instruments is a 16-bit non-inverting bus transceiver designed with a 3.3-V V<sub>CC operation, but with 5-V tolerant inputs. This high-speed transceiver belongs to the SN74LVC family, which ensures latch-up performance exceeds 250 mA per JESD 17, and it is optimized for low-voltage applications ranging from 1.65V to 3.6V. This makes it ideal for interfacing between different voltage levels within a system.

Featuring a bidirectional data path, the SN74LVC16245AGRDR provides two distinct sets of data inputs and outputs (A and B) for each direction. Direction control (DIR) and output enable (OE) inputs control the data flow. The DIR input determines the direction of data flow, whereas the OE input activates the outputs on the B port.

This device is designed for asynchronous communication between data buses. The control-function implementation minimizes external timing requirements. The SN74LVC16245AGRDR can be used in a wide variety of applications, including memory driver, clock driver, and bidirectional communication between data buses.

Packaged in a 48-pin TSSOP (Thin Shrink Small Outline Package), the SN74LVC16245AGRDR offers a reduced body size and thinner lead profile, which is ideal for space-constrained applications. Its balanced propagation delays and transition times further enhance its performance in high-speed systems.

Key features of the SN74LVC16245AGRDR include:

• Support for mixed-mode voltage operation on all ports
• IOFF support, which ensures no damaging current backflow through the device when it is powered down
• Control inputs VIH (High-level input voltage) and VIL (Low-level input voltage) levels are referenced to V<sub>CC of the device
• Bus hold on data inputs to eliminate the need for external pull-up/pull-down resistors
• Low power consumption, with a typical ICC of 10 µA maximum
• ESD protection exceeds JESD 22

The SN74LVC16245AGRDR is a versatile, high-performance component suitable for a variety of digital logic applications where low-voltage operation and interfacing with 5-V systems is required.
