INTEGRATED CIRCUITS 74LV240 Octal buffer/line driver; inverting (3-State) Product specification Supersedes data of 1997 Feb 19 IC24 Data Handbook 1998 May 20 Philips Semiconductors Product specification Octal buffer/line driver; inverting (3-State) FEATURES 74LV240 DESCRIPTION • Wide operating voltage: 1.0 to 5.5 V • 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 74LV240 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT240. The 74LV240 is an octal inverting buffer/line driver with 3-State outputs. The 3-State outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on nOE causes the outputs to assume a high impedance OFF-state. The 74LV240 is identical to the 74LV244 but has inverting outputs. 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 9.0 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.
