74LCX541 — Low Voltage Octal Buffer/Line Driver with 5V Tolerant Inputs and Outputs December 2013 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/withdrawal(1) ■ ±24 mA output drive (VCC = 3.0V) ■ Implements proprietary noise/ EMI reduction circuitry ■ Latch-up performance exceeds JEDEC 78 conditions ■ 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 of the resistor is determined by the current-sourcing capability of the driver. 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 microprocessors, 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 ...
