74LCX541 Low Voltage Octal Buffer/Line Driver with 5V Tolerant Inputs and Outputs February 2006 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 (VCC = 3.0V) ■ Implements patented noise/ EMI reduction circuitry ■ Latch-up performance exceeds JEDEC 78 conditions ■ ESD performance 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 advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation. – Human body model > 2000V – Machine model > 200V ■ Leadless Pb-Free DQFN package Ordering Information Order Number 74LCX541WM 74LCX541SJ 74LCX541BQX2 74LCX541MSA 74LCX541MTC 74LCX541MTC_NL3 Package Number M20B M20D Package Description 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide MLP020B Pb-Free 20-Terminal Depopulated Quad Very-Thin Flat Pack No Leads (DQFN), JEDEC MO-241, 2.5 x 4.5mm MSA20 MTC20 MTC20 20-Lead Shrink Small Outline Package (SSOP), JEDEC MO-150, 5.3mm Wide 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Pb-Free 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 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).
