Applications
The SN74LVC16T245DLG4 is ideal for interfacing between processors and memory subsystems operating at different voltage rails, such as bridging 3.3V microcontrollers to 1.8V DDR memory or 5V peripherals. It is widely used in FPGA development boards, embedded computing modules, and industrial controller backplanes where wide data bus voltage translation is required. Additional applications include multi-rail communication interfaces, test and measurement equipment bus isolation, and mixed-voltage SoC peripheral interfacing.

Frequently Asked Questions
What voltage levels can the SN74LVC16T245DLG4 translate between?
The SN74LVC16T245DLG4 supports two separate configurable power supply pins: VCCA for port A (1.65V to 3.6V) and VCCB for port B (1.65V to 5.5V). This allows bidirectional level translation between common logic standards such as 1.8V, 2.5V, 3.3V, and 5V, making it highly versatile for mixed-voltage system designs.
How is data direction controlled on the SN74LVC16T245DLG4?
The SN74LVC16T245DLG4 uses a common direction control (DIR) pin that sets the transmission direction for all 16 bits simultaneously. When DIR is high, data flows from port A to port B; when DIR is low, data flows from port B to port A. An output enable (OE) pin disables all outputs to a high-impedance state for bus sharing.
What package and lead finish does the SN74LVC16T245DLG4 use?
The SN74LVC16T245DLG4 is housed in a 48-pin SSOP package (JESD-30 code R-PDSO-G48) supplied in tube format. The G4 suffix confirms RoHS-compliant lead-free construction with e4 JEDEC moisture sensitivity level rating, meeting environmental compliance requirements for industrial and commercial applications.
What is the maximum output current of the SN74LVC16T245DLG4?
The SN74LVC16T245DLG4 provides a maximum output low-level current (IOL) of 8mA per channel and is specified to drive load capacitances up to 15pF. These drive characteristics are typical for the LVC family and are suitable for standard bus loads in embedded systems and PCB interconnects.
What are common alternatives to the SN74LVC16T245DLG4?
Functionally similar devices include the SN74LVCH16T245 (with bus-hold feature), SN74AVCH16T245 (wider voltage range up to 3.6V on both ports), and SN74LVC16245A (non-translating version). When selecting an alternative, verify the supply voltage ranges, direction control logic, and package compatibility to ensure a drop-in replacement.
