Features

The SN74LVC245ANSR is an octal bus transceiver from Texas Instruments that operates with a voltage range of 1.65 V to 3.6 V. It is designed for asynchronous communication between data buses and supports 3-state outputs, which allow for multiple transceivers to be connected to the same data lines. Key features include a low power consumption, with a maximum quiescent current (I_CC) of 10 µA, and it supports partial power-down applications with I_off circuitry. This component is compliant with JESD 78, ensuring it is latch-up performance resistant. It has a maximum data rate of 100 Mbps, making it suitable for high-speed data transfer applications. The device is characterized for operation from –40°C to 85°C, making it suitable for industrial applications. Additionally, the SN74LVC245ANSR features high output drive, with a capability of driving up to 24 mA at 3.3 V. It is available in a small-outline package, which is beneficial for space-constrained designs.

Pinout

The SN74LVC245ANSR is a non-inverting octal bus transceiver with 3-state outputs. It is typically housed in a 20-pin small-outline integrated circuit (SOIC) package. The primary function of this device is to enable bidirectional data flow between two buses and operate as a buffer. It features an output enable (OE) and a direction control (DIR) pin, which facilitate the control of data direction and activation of the device.
Key features include:
- 20 pins: The device has separate pins for power supply (V_CC), ground (GND), data inputs/outputs (A1-A8, B1-B8), an output enable pin (OE), and a direction control pin (DIR).
- Direction Control (DIR): Determines the direction of data flow. High usually allows data flow from A to B, while low allows data from B to A.
- Output Enable (OE): When low, the device is enabled, and when high, the outputs are in a high-impedance state, effectively disconnecting the bus.
The SN74LVC245ANSR is widely used for interfacing and buffering data signals in digital electronics applications.
