The 93S46 is designed as a very high speed 6 bit identity comparator.The device compares two words of up to six bits and indicates identity in less than 12ns. 93S46 is easily expandable to any word length by using either serial or parallel expansion techniques. When the enable input (E) is low, it forces the output low.
93S46 has three features. (1)Compares two 6-bit words in 12ns. (2)Easily expandable to any word size. (3)Active high enable for fast ripple expansion. Those are all the main features.
Some DC characteristics of 93S46 are AC characteristics are concluded into several points as follow. (1)Its power supply current would have the maximum value of 70mA with test conditions of Vcc=max. (2)Its propagation delay An or Bn to A=B tPLH would be min 3.0ns and max 17ns with test conditions of E=4.5V, other inputs=4.5V, test each input individully. (3)Its propagation delay An or Bn to A=B tPHL would be min 3.0ns and max 17ns with test conditions of E=4.5V, other inputs=4.5V, test each input individully. (4)Its propagation delay An or Bn to A=B tPLH would be min 3.0ns and max 14ns with test conditions of E=4.5V, other inputs=GND, test each input individully. (5)Its propagation delay An or Bn to A=B tPHL would be min 3.0ns and max 15ns with test conditions of E=4.5V, other inputs=GND, test each input individully. (6)Its propagation delay E to A=B tPLH would be min 2.0ns and max 10ns with test conditions of An=Bn. (7)Its propagation delay E to A=B tPHL would be min 2.0ns and max 10ns with test conditions of An=Bn.
Also some functional description about 93S46. It is a very high speed 6-bit identity comparator. The A=B output is high when the enable E is high and the two 6-bit words are equal. Equality is determined by exclusive-NOR circuits which individually compare the equivalent bits from each word. When any two of the equivalent bits from each word have different logic levels, the A=B output is low. And so on.
