簡介

The ZT487E devices are 5V differential data line transceivers for RS485/RS422 communication that consist of one driver and one receiver with high level of ESD protection. They are designed for balanced transmission lines interface that meet ANSI standard TIA/EIA-485-A and ISO 8482:1987(E) specifications.

The ZT487E devices spans out with half duplex, data rate guaranteed at 250K bit per second, and allow one-fourth of an unit load that fan out 128 devices sharing a common bus. The I/Os are enhanced-electrostatic discharge (ESD) protected, exceeding ±15kV Human Body Model (HBM).

規格:

● Meets or exceeds the requirements of ANSI Standard TIA/EIA-485-A and ISO 8482:1987(E) specifications for Vcc at +5V ±5%

● Low quiescent current - 0.5mA typ., 1mA max
● Low shutdown current (where applicable) - 0.01μA typical, 10μA max
● Guaranteed standard data rate 250Kbps
● Thermal shutdown protection
● -7V to +12V common-mode input voltage range
● Half-Duplex configuration
● Allows up to 1/4 unit load (128 devices) on the same common bus
● Controlled driver output slew rate and receiver input filtering
● Active-high driver enable and active-low receiver enable
● ESD Protection on bus terminals
-- ±15kV Human Body Model (HBM)
● Drop-in Replacements for MAX487E, SN75LBC182
● Standard fanout driving 1 unit load (32 devices) available on the ZT487E
