NJU6401B

The NJU6401B is a RS232C line driver/receiver composed of 3 drivers and 5 receivers.The  drivers  NJU6401B convert the input  of TTL level signals ioto RS232C level signals and limit the slew rate below 30V/s.The receivers accept the input levels bath of RS-232C standard minimum requirement level(±3V) and TTL level.Furthermore,the hysteresis circuit and noise filter incorporated  on each  receiver ensures noise-free operation.

Features of the NJU6401B are:(1)based on the RS232C standard; (2)3 drivers and 5 receivers; (3)low operating current; (4)driver output voltage:±25V; (5)receiver input voltage:±27V; (6)output impedance at power-off(driver):300(min); (7)slew rate(driver):30V/s(Max); (8)TTL-compatible input(driver); (9)TTL-compatible input/output(receiver); (10)hysteresis input(receiver); (11)noise filter on-chip(receiver); (12)package outline:DIP/DMP 20; (13)C-MOS technology.The each driver incorporate series resistance to keep the output impedance  to 300 or more during the power-off.This series resistance also protect the internal circuits against the overvoltage of ±25V impressed from outside.

The absolute maximum ratings of the NJU6401B can be summarized as:(1)supply voltage:-0.3 to +6.0V;(2)storage temperature:-65 to +150;(3)operating temperature:-20 to +75 ;(4)input voltage:±27V;(5)output voltage:-0.3V to Vcc +0.3V;(6)output current:±60mA;(7)power dissipation:500mW.The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics.
