Frequently Asked Questions
What is the TL16C554AIPN used for?
The TL16C554AIPN is a quad UART (Universal Asynchronous Receiver/Transmitter) IC used to add four independent serial communication channels to a system. It is widely used in industrial controllers, multi-port serial cards, PLCs, and embedded systems needing simultaneous RS-232 or RS-485 communication.
What are the key electrical specifications of TL16C554AIPN?
The TL16C554AIPN operates on a single 5V supply, supports baud rates up to 1.5 Mbps per channel, features 16-byte transmit and receive FIFOs per UART, and is rated for industrial temperature from -40°C to +85°C. It comes in a 44-pin PLCC package.
What package does the TL16C554AIPN come in and how many pins does it have?
The TL16C554AIPN is packaged in a 44-pin PLCC (Plastic Leaded Chip Carrier). The A suffix denotes the enhanced FIFO version, I denotes industrial temperature grade, and PN denotes the PLCC package style.
Is TL16C554AIPN RoHS compliant?
Yes, the TL16C554AIPN is RoHS compliant and lead-free. It meets EU RoHS Directive 2011/65/EU requirements, making it suitable for designs that require compliance with environmental regulations.
What are good alternatives or replacements for the TL16C554AIPN?
Compatible alternatives include the XR16C554 (Exar), ST16C554 (SIPEX/MaxLinear), and TL16C554BIFN (same function, different package). For higher integration, consider the TL16C754B which offers 64-byte FIFOs.
