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.

(VCC = 3.3V), 10µA ICC max. ■ Power down high impedance inputs and outputs ■ Supports live insertion/withdrawal(1) ■ ±24mA output drive (VCC = 3.0V) ■ Latch-up performance exceeds 500mA ■ ESD performance: – Human body model > 2000V – Machine model > 200V ■ Leadless DQFN package 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. General Description The LCX244 contains eight non-inverting buffers with 3-STATE outputs. The device may be employed as a memory address driver, clock driver and bus-oriented transmitter/receiver. The LCX244 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The LCX244 is fabricated with an advanced CMOS tech- nology to achieve high speed operation while maintain- ing CMOS low power dissipation. Ordering Information Note: 2. DQFN package available in Tape and Reel only. Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Note: 3. IO Absolute Maximum Rating must be observed. Recommended Operating Conditions(4) The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not recommend exceeding them or designing to absolute maximum ratings.
