The device includes circuitry to hold Q to a low logic level when the inputs are in an open condition. The VBB pin is a reference voltage output for the device. When the device is used in the single-ended mode, the unused input should be tied to VBB. This reference voltage can also be used to bias the input when it is ac coupled. When the VBB pin is used, place a 0.01-µF decoupling capacitor between VCC and VBB. Also, limit the sink/source current to 25°C (mW/°C) POWER RATING TA = 85°C (mW) SOIC SOIC-TSSOP Low-K 719 139 7 288 High-K 840 119 8 336 Low-K 469 213 5 188 High-K 527 189 5 211 THERMAL CHARACTERISTICS PARAMETER θJB Junction-to-board thermal resistance θJC Junction-to-case thermal resistance PACKAGE VALUE SOIC 79 SOIC-TSSOP 120 SOIC 98 SOIC-TSSOP 74 UNIT °C/W °C/W KEY ATTRIBUTES CHARACTERISTICS VALUE Internal input pulldown resistor 75 kΩ Moisture sensitivity level Level 1 Flammability rating (oxygen index: 28 to 34) UL 94 V-0 at 0.125 in ESD—human-body model 4 kV ESD—machine model 200 V ESD—charged-device model 2 kV Meets or exceeds JEDEC Spec EIA/JESD78 latchup test 2 Submit Documentation Feedback Copyright © 2008, Texas Instruments Incorporated Product Folder Link(s): SN65EL16 SN65EL16 www.ti.com............................................................................................................................................................................................

Electrical parameters are assured only over the declared operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit values are applied individually under normal operating conditions and are not valid simultaneously. Input and output parameters vary 1:1 with VCC. VEE can vary +0.8 V /–0.5 V. Outputs are terminated through a 50-Ω resistor to VCC – 2 V. VIHCMR min varies 1:1 with VEE; VIHCMR max varies 1:1 with VCC. The VIHCMR range is referenced to the more-positive side of the differential input signal. Normal operation is obtained if the HIGH level falls within the specified range and the peak-to-peak voltage lies between VPP min and 1 V.
