SN74LVC373AGQNR is a general-purpose 8-bit 3-state bus buffer, compatible with both CMOS and TTL input levels. Part of the Texas Instruments low-voltage CMOS family, these devices are designed to accommodate applications where very low power consumption and low supply voltage level is important; they feature an extended operating temperature range with an operating voltage of 1.8V to 3.3V. The SN74LVC373AGQNR devices offer logic level translation between two distinct nodes, translating a low voltage push-pull signal into a low-voltage open-drain signal, and vice versa. A series of three-state outputs provide a bus line control of branch-on and branch-off applications.

The SN74LVC373AGQNR is a CMOS 8-bit latch with 3-state output buffers. The latch is enabled when the latch enable (LE) is high, and the data is latched on the rising edge of the clock (CP). The output buffers have both an active low enable (OE) and 3-state (3S) input, the OE and 3S pins must both be high in order to drive the output. With the OE (Output Enable) high, the 8-bit data present on the 8-bit data inputs (DI0 – DI7) will drive the 8-bit output buffers (Q0 – Q7). With OE low, the outputs will be in a high impedance state.

The SN74LVC373AGQNR devices offer several features, including two active-low enable inputs (LE and OE). LE, the latch enable, controls the latching of data on the rising edge of CP. When the LE pin is low, the data present on the 8-bit data inputs is latched, and the output buffers will be enabled by OE or 3S. OE, the output enable, controls the output enable and 3-state logic. If OE is low, the outputs are in a high impedance state independent of current on the 3S input. If both OE and 3S are high, the outputs will be enabled and the data will be driven onto the outputs.

The SN74LVC373AGQNR devices provide reliable operation over the full industrial temperature range of -40°C to +85°C, and are provided in either SOIC-14, TSSOP-14, or TSSOP-16 packages. These devices benefit from an ultra low-power dissipation making them suitable for battery-powered applications, and are designed to consume very little power when operated from a 1.8V, 2.5V, or 3.3V supply.

The SN74LVC373AGQNR devices are ideal for a range of applications that require low-voltage level translation and data buffering. These devices are frequently used in automotive, medical, consumer, and industrial applications that require data buffering, including smart sensor interfaces and audio/video multiplexers. Moreover, they are commonly used in automotive and networking applications, such as low-voltage voltage level shift buffers, I2C, and SPI bus bridge controllers.

In conclusion, the SN74LVC373AGQNR is an excellent choice for applications that require low-voltage translation and data buffering. Its low-power dissipation and extended operating temperatures make it a great choice for industrial and automotive applications. With a wide range of features, such as two active-low enable inputs, latch enable, and output enable, these devices can easily adapt to a variety of applications.
