The SN74ALVTH16240GR is an integrated circuit (IC) categorized under the logic family of Buffers, Drivers, Receivers, and Transceivers. It is used to convey digital signals in various circuit and system designs and can be found in applications such as consumer, commercial, industrial, automotive, and military. The SN74ALVTH16240GR falls into the signal integrity class of bus buffers, which provide shielded data pathways between multi-functional devices or subsystems in order to ensure that transmitted digital signals remain consistent, stable, and uninterrupted.

The SN74ALVTH16240GR consists of sixteen tri-state non-inverting buffers, where each buffer has two input terminals (A and B), one output terminal (Y), and one enable terminal (E). Logic ‘1’ is applied to the enable terminal and will enable the output terminal (Y) to accept data from the A terminal. Conversely, a logic ‘0’ applied to the enable terminal will enable the output terminal (Y) to accept data from the B terminal. The two data inputs can be thought of as two independent data buses and the single enable terminal controls the output of the buffer.

The SN74ALVTH16240GR circuitry is composed of CMOS technology. The three-state logic buffer consists of four different segments, CMOS and BiCMOS enable, NAND-AND enable, and transistor drive. Each segment of the circuit contains components consisting of transistors, resistors, capacitors, and/or diodes. The buffer is designed to be capable of driving both CMOS and TTL input/output logic devices.

The SN74ALVTH16240GR is equipped with a set of power connection pins that are connected to the VCC and GND. VCC supplies power to all the circuitry and GND returns the current from the operation and grounds the circuit. A voltage level between 3.0 and 5.5 VDC is required for circuit operation.

The SN74ALVTH16240GR also includes a busy LED diode that is used to notify users in the event that all sixteen buffers are in a standby, or idle state. The power and ground pins are needed to power the LED and the busy LED input pin is tied to ground. When all sixteen buffers are in use, the busy LED will be lit. In this way, it is possible to monitor the SN74ALVTH16240GR’s operation and ensure that data is being transferred properly.

In addition to the busy LED, the SN74ALVTH16240GR includes protection circuitry in the form of over-voltage protection, ESD protection, and over-temperature protection. Over-voltage protection is used to protect against transients in the power supply and prevent permanent damage to the device. ESD protection prevents damage due to high voltage spikes caused by electrostatic discharge. Over-temperature protection helps protect against thermal runaway, which can shorten the life expectancy of the device.

The SN74ALVTH16240GR is generally used in circuits that require several devices or subsystems to exchange digital data. With sixteen non-inverting buffers, the SN74ALVTH16240GR helps ensure that data is transferred at the highest possible signal integrity and free of interference and disruption. The device is versatile and can be used in various circuit and system designs, providing high-speed connections between components, as well as protection against voltage and temperature transients.
