This document describes the data sheet of Harris Semiconductor's SCHS251D. The product features include buffered inputs, ESD protection exceeding 2kV, SCR-latchup-resistant CMOS process and circuit design, fast addition with reduced power consumption, balanced propagation delays, etc.
The document describes the CD54/74AC283 and CD54/74ACT283 as 4-bit binary adders with fast carry that utilize Advanced CMOS Logic technology. These devices add two 4-bit binary numbers and generate a carry-out bit if the sum exceeds 15, supporting both active-HIGH and active-LOW operands.
| Supply Voltage Range (AC Types) | 1.5V to 5.5V |
|---|---|
| Supply Voltage Range (ACT Types) | 4.5V to 5.5V |
| Output Drive Current | +24mA |
| Fanout Capability | 15 FAST™ ICs |
| ESD Protection | 2kV |
The device can be used with either all active-HIGH operands (positive logic) or with all active-LOW operands (negative logic).
The maximum junction temperature for a plastic package is 150°C.
