To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

The device is designed for low volt- age (2.5V or 3.3V) VCC applications with capability of inter- facing to a 5V signal environment. The device is byte controlled. Each byte has separate control inputs which could be shorted together for full 16-bit operation. The T/R inputs determine the direction of data flow through the device. The OE inputs disable both the A and B ports by placing them in a high impedance state. In addition, A and B port datapath pins have built-in resis- tors to GND allowing the pins to float without any increase in ICC current. This feature is intended to address modular and space constrained applications where additional space consumed by external resistors is not available. The LCXP16245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintain- ing CMOS low power dissipation. Features ■5V tolerant inputs and outputs ■2.3V–3.6V VCC specifications provided ■ I/O pull-down resistors terminate inactive busses ensur- ing a stable bus state ■5.5 ns tPD max (VCC 3.3V), 20 PA ICC max ■Power down high impedance inputs and outputs ■Supports live insertion/withdrawal (Note 1) ■r24 mA output drive (VCC 3.0V) ■Pinout compatible with 74 series 16245 ■Latch-up performance exceeds 500 mA ■ESD performance: Human body model ! 2000V Machine model ! 200V Note 1: To ensure the high-impedance state during power up or down OE should be tied to VCC through a pull-up resistor: the minimum value or the resistor is determined by the current-sourcing capability of the driver. Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

Functional Descriptions The LCXP16245 contains sixteen non-inverting bidirec- tional buffers with 3-STATE outputs. the device is byte con- trolled. Each byte has separate control inputs which can be shorted together for full 16-bit operation. The T/R inputs determine the direction of data flow through the device. The OE inputs disable both the A and B ports by placing them in a high impedance state. The pulldown resistor (30K: normal) to GND is active only when the outputs are 3-STATED (OE HIGH). When the outputs become active (OE LOW) the resistor is removed from the circuit.
