XR16L2552 - 2.25V TO 5.5V DUART

Description

The XR16L2552 (L2552) is a dual universal asynchronous receiver and transmitter (UART) with 5 volt tolerant inputs.

The XR16L2552 is an improved version of the ST16C2552 UART with lower operating voltages and 5 volt tolerant inputs.

Features

  • 2.25 to 5.5 Volt Operation.
  • 5 Volt Tolerant Inputs.
  • Pin-to-pin and functionally compatible to National PC16552.
  • Pin-to-pin Compatible to Exar’s ST16C2552, XR16L2752 and XR16C2852 in the 44-PLCC.
  • 2 Independent UART Channels.

The XR16L2552 is an improved version of the ST16C2552 UART with lower operating voltages and 5 volt tolerant inputs. The L2552 provides enhanced UART functions with 16 byte TX and RX FIFOs, automatic hardware (RTS/CTS) and software (Xon/Xoff) flow control, and a complete modem control interface. Onboard status registers provide the user with error indications and operational status. Indepedendent programmable baud rate generators are provided to select transmit and receive clock rates up to 3.125Mbps. An internal loop-back capability allows onboard diagnostics.
