INTEGRATED CIRCUITS 74LV688 8-bit magnitude comparator Product specification Supersedes data of 1997 May 15 IC24 Data Handbook 1998 Jun 23 Philips Semiconductors Philips Semiconductors Product specification 8-bit magnitude comparator 74LV688 FEATURES Wide operating voltage: 1.0 to 5.5V Optimized for low voltage applications: 1.0V to 3.6V Accepts TTL input levels between VCC = 2.7V and VCC = 3.6V Typical VOLP (output ground bounce) < 0.8V at VCC = 3.3V, Typical VOHV (output VOH undershoot) > 2V at VCC = 3.3V, Compare two 8-bit words Output capability: standard ICC category: MSI QUICK REFERENCE DATA SYMBOL tPHL/tPLH CI CPD PARAMETER Propagation delay Pn, Qn to P=Q Input capacitance Power dissipation capacitance per gate Tamb = 25°C Tamb = 25°C DESCRIPTION The 74LV688 is a high-speed Si-gate CMOS device, pin compatible with the 74HC/HCT688 The 74LV688 is an 8-bit magnitude comparator. It performs comparisons of two 8-bit binary or BCD words. The output provides P = Q (equal-to). CONDITIONS CL = 15pF VCC = 3.3V TYPICAL 17 3.5 UNIT ns pF pF VI = GND to VCC1 22 NOTE: 1. CPD is used to determine the dynamic power dissipation (PD in mW): PD = CPD × VCC2 × fi + S (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; S (CL × VCC2 × fo) = sum of outputs.
