DS34LV87T Datasheet | National Semiconductor

Description The DS34LV87T is a high speed quad differential CMOS driver that meets the requirements of both TIA/EIA-422-B and ITU-T V.11. The CMOS DS34LV87T features low static ICC of 100 µA max which makes it ideal for battery powered and power conscious applications. The TRI-STATE ® enable, EN, allows the device to be disabled when the device is not in use to minimize power. The dual enable scheme allows for flexibility in turning devices on or off. Protection diodes protect all the driver inputs against electrostatic discharge. The driver and enable inputs (DI and EN) are patible with LVTTL and LVCMOS devices. Differential outputs have the same VOD (≥2V) guarantee as the 5V version. The outputs have enhanced ESD Protection providing greater than 7 k V tolerance. Features n Meets TIA/EIA-422-B (RS-422) and ITU-T V.11 remendation n Interoperable with existing 5V RS-422 networks n Guaranteed VOD of 2V min over operating conditions n Balanced output crossover for low EMI (typical within 40 m V of 50% voltage level) n Low power design (330 µW 3.3V static) n ESD ≥ 7 k V on cable I/O pins (HBM) n Industrial temperature range n Guaranteed AC parameter: - Maximum driver skew: 2 ns - Maximum transition time: 10 ns n Pin patible with DS26C31 n Available in SOIC packaging Connection Diagram Dual-In-Line Package Truth Table Enables EN L H H L = Low logic state X = Irrelevant H = High logic state Z = TRI-STATE Input DI X H L DO+ Z H L Outputs DO- Z L H DS012645-1 Top View Order Number DS34LV87TM or DS34LV87TN See NS Package Number M16A or N16A TRI-STATE ® is a registered trademark of National Semiconductor Corporation. © 1998 National Semiconductor Corporation DS012645 .national.
