Description
Key features include:
- Dual-supply operation with A-port and B-port operating at different voltage levels.
- High-speed operation with low power consumption.
- Direction control for data flow management, allowing data to move from A to B or B to A.
- A 3-state output feature that helps in bus-oriented applications, which can be controlled with the output enable (OE) pin.
- Integrated ESD protection enhances robustness against electrostatic discharges.
The SN74AVCH16T245GR is typically used in applications requiring translation between different voltage levels, such as interfacing between microcontrollers and peripheral devices. Its compact packaging and robust functionality make it a reliable choice for designers needing efficient level shifting and buffering.
Equivalent
1. NXP 74AVC16T245 - 16-bit dual-supply translating transceiver.
2. ON Semiconductor FXLA2205 - 16-bit multi-supply voltage level translator.
3. ADI ADG3308 - 8-channel bidirectional logic level translator.
These alternatives offer similar voltage translation and bidirectional data flow capabilities, but always verify electrical specifications and pin compatibility for replacements.
Features
1. Voltage Range: Supports dual-supply operation, with one supply ranging from 1.2 V to 3.6 V and another from 1.65 V to 5.5 V, enabling level translation.
2. Data Rate: Capable of high-speed data transfer up to 380 Mbps for 1.8 V to 3.3 V translation.
3. Low Power Consumption: Features low static and dynamic power dissipation, contributing to efficient operation.
4. Bus-Hold: Includes bus-hold capabilities on the data inputs to eliminate the need for external pull-up or pull-down resistors.
5. Ioff Support: Prevents backflow of current into the device when it is powered down, protecting the circuits on the bus.
6. Latch-Up Performance: Exceeds 100 mA per JESD 78, Class II.
7. ESD Protection: Offers high ESD protection with ratings up to 2000 V per the Human-Body Model and 1000 V per the Charged-Device Model.
These features make the SN74AVCH16T245GR suitable for applications requiring high-speed and low-power level translation between different logic levels.
Pinout
The SN74AVCH16T245GR comes in a TSSOP (Thin Shrink Small Outline Package) with 48 pins. The pin configuration includes:
- 16 data bus lines for each direction (A1 to A16 and B1 to B16).
- Two separate supply voltage pins (VCCA for A-side and VCCB for B-side) to allow voltage level translation.
- Two output enable pins (/OE1 and /OE2), which control the direction and state of the transceivers.
- A direction control pin (DIR), which selects the direction of data flow.
The device is designed for asynchronous communication between data buses, and it supports partial power-down applications, providing isolation when either VCC is at 0 V. The SN74AVCH16T245GR is widely used in applications requiring low power consumption and high speed.
