| 100360 Low Power Dual Parity Checker/Generator March 1998 Revised August 2000 100360 Low Power Dual Parity Checker/Generator General Description The 100360 is a dual parity checker/generator. Each half has nine inputs; the output is HIGH when an even number of inputs are HIGH. One of the nine inputs (Ia or Ib) has the shorter through-put delay and is therefore preferred as the expansion input for generating parity for 16 or more bits. The 100360 also has a Compare (C) output which allows the circuit to compare two 8-bit words. The C output is LOW when the two words match, bit for bit. All inputs have 50 k pull-down resistors. Features s Lower power than 100160 s 2000V ESD protection s Pin/function compatible with 100160 s Voltage compensated operating range = -4.2V to -5.7V s Min to Max propagation delay 35% tighter than 100160 s Available to industrial grade temperature range Ordering Code: Order Number 100360PC 100360QC 100360QI Package Number N24E V28A V28A Package Description 24-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-010, 0.400 Wide 28-Lead Plastic Lead Chip Carrier (PLCC), JEDEC MO-047, 0.450 Square 28-Lead Plastic Lead Chip Carrier (PLCC), JEDEC MO-047, 0.450 Square Industrial Temperature Range (-40C to +85C) Devices also available in Tape and Reel.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum rating. The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 2: ESD testing conforms to MIL-STD-883, Method 3015.

Since these values normally occur at the temperature extremes, additional noise immunity and guardbanding can be achieved by decreasing the allowable system operating ranges. Conditions for testing shown in the tables are chosen to guarantee operation under "worst case" conditions.
