The 74VCX163245 is a 16-bit bidirectional translator with a 3-state output from Fairchild/ON Semiconductor. It is designed for high-speed, low-power operation, making it suitable for various digital logic applications.
Applications:
- Voltage translation between different logic levels (e.g., 3.3V to 5V or 1.8V to 3.3V)
- Memory interfaces
- Bus isolation
- Data transmission in high-speed digital systems
- Level shifting in mixed-voltage systems
Features:
- Low static and dynamic power consumption
- High-speed operation: tpd = 3.0 ns (typical) at 3.3V
- Wide operating voltage range: 1.65V to 5.5V
- 3-state outputs for bus isolation
- TTL compatible inputs
- Bus hold on data inputs eliminates the need for external pull-up resistors
- Available in various packages, including TSSOP and BGA
Benefits:
- Enables seamless communication between devices operating at different voltage levels.
- Reduces power consumption in portable and energy-sensitive applications.
- Improves system performance due to fast propagation delays.
- Provides bus isolation to prevent loading effects.
- Simplifies system design by eliminating the need for external components.
- Offers flexibility in package selection to meet different application requirements.
Additional Details:
The 74VCX163245 features a control pin (DIR) to determine the direction of data flow. When DIR is HIGH, data flows from A to B; when DIR is LOW, data flows from B to A. The output enable (OE) pin controls the 3-state outputs. When OE is LOW, the outputs are enabled; when OE is HIGH, the outputs are in the high-impedance state.
This translator is commonly used in applications where different voltage levels need to interface, such as connecting a 3.3V microcontroller to a 5V peripheral device. Its low power consumption makes it suitable for battery-powered devices.
