INTEGRATED CIRCUITS 74LV241 Octal buffer/line driver (3-State) Product specification Supersedes data of 1997 Feb 19 IC24 Data Handbook 1998 May 20 Philips Semiconductors Product specification Octal buffer/line driver (3-State) 74LV241 FEATURES DESCRIPTION • Optimized for low voltage applications: 1.0 to 3.6 V • Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V • Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V, The 74LV241 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT241. The 74LV241 is an octal non-inverting buffer/line driver with 3-State outputs. The 3-State outputs are controlled by the output enable inputs 1OE and 2OE. Tamb = 25°C • Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V, Tamb = 25°C • Output capability: bus driver • ICC category: MSI QUICK REFERENCE DATA GND = 0 V; Tamb = 25°C; tr = tf ≤ 2.5 ns PARAMETER SYMBOL CONDITIONS tPHL/tPLH Propagation delay 1An to 1Yn; 2An to 2Yn CL = 15 pF; VCC = 3.3 V CI Input capacitance CPD Power dissipation capacitance per buffer VCC = 3.3 V VI = GND to VCC1 TYPICAL UNIT 8.0 ns 3.5 pF 30 pF NOTE: 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 capacitance in pF; fo = output frequency in MHz; VCC = supply voltage in V; (CL VCC2 fo) = sum of the outputs.
