1 / 14 page ©2006 Fairchild Semiconductor Corporation 1 www.fairchildsemi.com February 2006 74LCX541 Rev. 2.0.0 74LCX541 Low Voltage Octal Buffer/Line Driver with 5V Tolerant Inputs and Outputs Features ■ 5V tolerant input and outputs ■ 2.3V–3.6V VCC specifications provided ■ 6.5ns tPD max (VCC = 3.3V), 10µA ICC max ■ Power-down high impedance inputs and outputs ■ Supports live insertion/withdrawal1 ■ ±24 mA output drive (V CC = 3.0V) ■ Implements patented noise/ EMI reduction circuitry ■ Latch-up performance exceeds JEDEC 78 conditions ■ ESD performance – Human body model > 2000V – Machine model > 200V ■ Leadless Pb-Free DQFN package General Description The LCX541 is an octal buffer/line driver designed to be employed as memory and address drivers, clock drivers and bus oriented transmitter/receivers. The LCX541 is a non inverting option of the LCX540. This device is similar in function to the LCX244 while providing flow-through architecture (inputs on opposite side from outputs). This pinout arrangement makes this device especially useful as an output port for micropro- cessors, allowing ease of layout and greater PC board density. The LCX541 is designed for low voltage applications with capability of interfacing to a 5V signal environment. The LCX541 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation. Ordering Information Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code. Pb-Free package per JEDED J-STD-020B. Notes: 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 of the resistor is determined by the current-sourcing capability of the driver. 2. DQFN package available in Tape and Reel only. 3. “_NL” indicates Pb-Free package (per JEDEC J-STD-020B). Device available in Tape and Reel only.
