The 74ALVCH16245TTR is a device in the family of Buffer, Driver, Receiver, Transceiver logic series. It is suitable for use in high speed logic systems, networking, data transmission and telecommunication applications.

Application Field

The 74ALVCH16245TTR is a low-voltage and low-power Transmit-Receive (TR) transceiver. Its main application field is in high-speed applications, such as digital logic design and system interconnections. This logic series transceiver provides two Differential Non-Return-to-Zero (NRZ) drivers, two Differential NRZ receivers and two three-state current-mode outputs.

The low-voltage device, with a Schottky transistor gate structure, can handle data rates up to 110 Mb/s in both transmit and receive directions. The 74ALVCH16245TTR also has four power-down mode feature. The push-pull output of the 74ALVCH16245TTR, which is low-noise, offers reduced noise, power consumption, and electromagnetically interference.

Working Principle

The 74ALVCH16245TTR consists of two non-inverting differential NRZ receivers, two inverting differential NRZ drivers, and two three-state current-mode outputs. The NRZ receivers detect and convert incoming logic level signals into the reverse logic level state. The NRZ drivers source and sink logic level signals to the outputs. The three-state current-mode outputs allow the outputs to be either high-impedance or transmitting data in the logic level of their respective output pins. The 74ALVCH16245TTR is designed with a Schottky transistor gate structure that reduces the supply current, power consumption, and electromagnetic interference.

The 74ALVCH16245TTR has a wide supply voltage range of 4.5V to 5.5V and a maximum operating temperature of 85°C. The logic levels of the device are TTL compatible and its input and output logic levels are compatible with common logic families (LSTTL, TTL and CMOS logic). Additionally, the device has an on-chip ESD protection diode, which provides protection against transient disturbances.

The 74ALVCH16245TTR is available in different package types, including 16-Pin TSSOP, 16-Pin Narrow SOIC, and 16-Pin MSOP. The TSSOP package has an exposed pad that must be soldered internally to the system ground potential. The 16-pin Narrow SOIC package has end pads and the 16-pin MSOP package has an external power-down pin.

The 74ALVCH16245TTR is an ideal device for applications requiring high-speed data transmission, data conversion, and error checking. It offers the low power, low voltage capability of a conventional logic series device, with the added advantage of being able to handle higher data speeds. It is able to send and receive data at speeds of up to 110 Mb/s in both transmit and receive directions. In addition, it has four power-down modes, which allow for further power savings.
