The 74LVTH646MTC is a 7-bit, non-inverting CMOS translator/buffer with a 3-state output. It is capable of translating signals from 3.3V to 5V, and can drive up to 15 LS-TTL loads. It is designed to provide a low-power buffer transfer in 1.8V to 3.3V environments. Because of its low power draw, the 74LVTH646MTC is used in a variety of automotive, industrial and consumer electronics applications.

The 74LVTH646MTC is optimized for applications needing bidirectional level shifting between different voltage systems. It can provide levels of compatibility between 3V and 5V logic families. This device features a 3-state output, which can enable many-to-one data bus applications. The open-drain collector of the 74LVTH646MTC HCT removes the need for external pull-up resisters, increasing the speed of data transfers and reducing the power requirements within a system.

The 74LVTH646MTC receives data from TTL-level inputs and drives High-Level CMOS or LSTTL outputs then outputs data at one of two selectable voltage levels of 5V or 3.3V. The active-low Configuration Input sets the output voltage level of the device. The 74LTVTH646MTC also includes a Bidirectional 3-state Output, which can be used to enable data transfers across multiple buses. If a logic ‘1’ is applied to the output enable pin (OE), the device will pass data from the source bus to the load bus.

The 74LVTH646MTC has a low-voltage operation with a low operating current that is specified over the full temperature range and power supply range. This device has a low propagation delay times, typically 10 ~ 20 ns, and no bus-hold circuitry is needed. In addition, the open-drain output eliminates the need of external pull-up resistors. It is well suited to support a variety of applications such as system timers, address/data multiplexers, address decoders, data buffers, and line length extensions.

In summary, the 74LVTH646MTC is a 7-bit, non-inverting CMOS translator/buffer with a 3-state output designed for use in a variety of applications that require bidirectional level shifting between different voltage systems. It is especially well-suited for low-power operations and features a low operating current for its wide temperature range. Its open-drain output removes the need for external pull-up resistors with its bidirectional 3-state output enabling data transfers across multiple buses. All of these features make the 74LVTH646MTC an ideal device to support applications such as system timers, address/data multiplexers, address decoders, data buffers, and line length extensions.
