The CD74FCT16245CTMT is a 16-bit non-inverting transceiver from Harris Corporation's FCT logic family, designed for high-speed bidirectional data transfer in 5V systems. It operates from a 4.5V to 5.5V supply and provides 3-State outputs for bus-oriented applications. With a strong output current of 32mA source and 64mA sink, it can drive heavily loaded buses with excellent signal integrity. The device is specified for -40°C to +85°C industrial temperature range and comes in a 48-pin TFSOP package. Its combination of speed, drive strength, and wide temperature range makes it suitable for networking, automotive, and industrial applications.
- High Sink Current (64mA): Drives low-impedance loads and long traces, maintaining signal quality in demanding environments.
- Industrial Temperature Range: Guaranteed operation from -40°C to +85°C for automotive and factory automation.
- 16-Bit Width in Single Package: Reduces component count and PCB area compared to using two 8-bit transceivers.
- FCT Family Speed: Provides fast, predictable propagation delays for high-frequency bus operation.
Wide Bus Interfacing in Networking Equipment
In routers and switches, the CD74FCT16245CTMT handles 16-bit data paths between the forwarding engine and memory. The high 64mA sink current ensures signal integrity on long PCB traces, reducing bit errors in high-throughput environments.
Dual-Channel Data Acquisition
In data acquisition systems, this transceiver can buffer two independent 8-bit sensor data streams. The 3-State outputs allow the ADC and DAC to share a common microcontroller bus without additional multiplexing logic.
Industrial Motor Control Feedback
In servo motor drives, the device buffers encoder position data to the DSP controller. The industrial temperature range (-40°C to +85°C) ensures reliable operation in factory floor environments with heat and vibration.
Automotive Infotainment Bus
In car infotainment systems, this transceiver connects the main processor to display and audio modules. The fast propagation delay supports high-resolution video data transfer without visible artifacts.
FPGA Configuration Interface
When configuring FPGAs from external flash memory, this buffer can drive the configuration data lines. The 32mA source capability ensures clean logic levels even with multiple FPGA loads on the same bus.
Telecom Line Card Redundancy
In redundant telecom systems, the transceiver allows switching between primary and backup line cards. The 3-State outputs enable seamless hot-swapping without disrupting the active data path.
