DS34LV87TMX/NOPB Texas Instruments RS-422接口集成电路 Enhanced CMOS Quad Diff Line Dvr

1FEATURES DESCRIPTION

The DS34LV87T is a high speed quad differential • Meets TIA/EIA-422-B (RS-422) and ITU-T V.11

CMOS driver that meets the requirements of both Recommendation TIA/EIA-422-B and ITU-T V.11. The CMOS

• Interoperable With Existing 5V RS-422 DS34LV87T features low static ICC of 100 μA max

Networks which makes it ideal for battery powered and power

• Ensured VOD of 2V Min Over Operating conscious applications. The TRI-STATE enable, EN,

Conditions allows the device to be disabled when the device is

not in use to minimize power. The dual enable

• Balanced Output Crossover for Low EMI scheme allows for flexibility in turning devices on or (Typical Within 40 mV of 50% Voltage Level) off.

• Low Power Design (330 μW @ 3.3V Static)

Protection diodes protect all the driver inputs against

• ESD ≥ 7 kV on Cable I/O Pins (HBM) electrostatic discharge. The driver and enable inputs

• Industrial Temperature Range (DI and EN) are compatible with LVTTL and

• Ensured AC Parameter: LVCMOS devices. Differential outputs have the same

VOD (≥2V) ensure as the 5V version. The outputs

– Maximum Driver Skew: 2 ns have enhanced ESD Protection providing greater

– Maximum Transition Time: 10 ns than 7 kV tolerance.

• Pin Compatible With DS26C31

• Available in SOIC Packaging
