1. CHARACTERISTICS AND SPECIFICATIONS
ABSOLUTE MAXIMUM RATINGS
WARNING: Operations 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.
RECOMMENDED OPERATING CONDITIONS
Notes: 1. TV+ must not exceed RV+ by more than 0.3 V.
2. Power consumption while driving line load over operating temperature range. Includes IC and load.
Digital input levels are within 10% of the supply rails and digital outputs are driving a 50 pF capacitive
load.
3. Typical consumption corresponds to 50% ones density and medium line length at 5.0 V.
4. Maximum consumption corresponds to 100% ones density and maximum line length at 5.25 V.
DIGITAL CHARACTERISTICS (TA = -40°C to 85°C; TV+, RV+ = 5.0 V ±5%; GND = 0 V)
Notes: 5. This specification guarantees TTL compatibility (VOH = 2.4 V @ IOUT = -40 ∝A).
6. Output drivers are TTL compatible and will drive CMOS logic levels into a CMOS load.
