INTEGRATED CIRCUITS 74LV541 Octal buffer/line driver (3-State) Product specification Supersedes data of 1997 Mar 04 IC24 Data Handbook 1997 Jun 10 Philips Semiconductors Product specification Octal buffer/line driver (3-State) 74LV541 FEATURES DESCRIPTION • Optimized for Low Voltage applications: 1.0 to 3.6V • Accepts TTL input levels between VCC = 2.7V and VCC = 3.6V • Typical VOLP (output ground bounce) 0.8V @ VCC = 3.3V, The 74LV541 is a low–voltage CMOS device and is pin and function compatible with 74HC/HCT541. Tamb = 25°C The 74LV541 is an octal non-inverting buffer/line driver with 3-State outputs. The 3-State outputs are controlled by the output enable inputs OE1 and OE2. Tamb = 25°C A HIGH on OEn causes the outputs to assume a high impedance OFF–state. • Typical VOHV (output VOH undershoot) 2V @ VCC = 3.3V, • Non-inverting outputs • Output capability: bus driver • ICC category: MSI QUICK REFERENCE DATA GND = 0V; Tamb = 25°C; tr = tf 2.5 ns PARAMETER SYMBOL tPHL/tPLH Propagation delay An to Yn CI Input capacitance CPD CONDITIONS CL = 15pF VCC = 3.3V Power dissipation capacitance per buffer VI = GND to VCC 1 TYPICAL UNIT 10 ns 3.5 pF 37 pF NOTES: 1. CPD is used to determine the dynamic power dissipation (PD in µW) PD = CPD VCC2 fi (CL VCC2 fo) where: fi = input frequency in MHz; CL = output load capacity in pF; fo = output frequency in MHz; VCC = supply voltage in V; (CL VCC2 fo) = sum of the outputs.
