1 / 6 page  TLF6530 June 1989 5485DM5485DM7485 4-Bit Magnitude Comparators General Description These 4-bit magnitude comparators perform comparison of straight binary or BCD codes Three fully-decoded decisions about two 4-bit words (A B) are made and are externally available at three outputs These devices are fully expand- able to any number of bits without external gates Words of greater length may be compared by connecting compara- tors in cascade The A l B A k B and A e B outputs of a stage handling less-significant bits are connected to the cor- responding inputs of the next stage handling more-signifi- cant bits The stage handling the least-significant bits must have a high-level voltage applied to the A e B input The cascading paths are implemented with only a two-gate-level delay to reduce overall comparison times for long words Features Y Typical power dissipation 275 mW Y Typical delay (4-bit words) 23 ns Y Alternate MilitaryAerospace device (5485) is available Contact a National Semiconductor Sales OfficeDistrib- utor for specifications Connection Diagram Dual-In-Line Package TLF6530 – 1 Order Number 5485DMQB 5485FMQB DM5485J DM5485W or DM7485N See NS Package Number J16A N16E or W16A C1995 National Semiconductor Corporation RRD-B30M105Printed in U S A |
