1 CHARACTERISTICS AND SPECIFICATIONS
ABSOLUTE MAXIMUM RATINGS WARNING: Operation at or beyond these limits may result in
permanent damage to the device. Normal operation is not guaranteed at these extremes.

Notes: 1. Transient currents of up to 100 mA will not cause SCR latch-up. Also TTIP, TRING, TV+ and TGND can
withstand a continuous current of 100 mA.

Notes: 2. TV+ must not exceed RV+ by more than 0.3 V.
3. Power consumption figures assume device is driving line load over operating temperature range. The
consumption of both the IC and the load are included. Digital input levels are within 10% of the supply
rails and digital outputs are driving a 50 pF capacitive load.
4. Typical consumption corresponds to 50% ones density and medium line length at 5.0 V.
5. Maximum consumption corresponds to 100% ones density and maximum line length at 5.25 V.

Notes: 6. This specification guarantees TTL compatibility (VOH = 2.4 V @ IOUT = -40 µA).
7. Output drivers are TTL compatible and will drive CMOS logic levels into a CMOS load.
