Part Description: Relay driver IC


Part Details:

74ACT8244 RELAY DRIVER IC s OPERATES 4 LATCHES RELAIS, 1 SINGLE SIDE STABLE RELAY AND 1 LED s VERY LOW POWER CONSUMPTION s TTL COMPATIBLE INPUT THRESHOLDS s IMPROVED LATCH-UP IMMUNITY UP TO 300mA s OPERATING VOLTAGE RANGE: TSSOP VCC(OPR) = 4.25V to 5.25V s AVAILABLE IN TSSOP-20 PACKAGE ORDER CODES DESCRIPTION PACKAGE TUBE T & R The device is a relais driver for line card TSSOP 74ACT8244TTR application. It is able to operate four latchingrelais, one single side stable relay and one LEDconnected either to GND or VCC. All the outputs PIN CONNECTION can be set to LOW with the RST input as shown inthe true table. All inputs and outputs are equippedwith protection circuits against static discharge,giving them 2KV ESD immunity and transientexcess voltage.
