SN54AS645J Product Details

SN54AS645J Overview


An interesting CDIP package is used. With TTL outputs, bus transceiver can be used. The 1 elements all play a role. Logic device with 20 different terminations. There is a requirement for 5V of supply voltage. This electronic part belongs to the AS family of parts. This electric component comes with 20 pins. Through Hole applications can be used with digital buffer. A 20-pin connector is used. An enhanced bus transceiver with 2 ports is available. An electrical supply with 5V is recommended. There is usually a TUBE package available. Using 5V supply voltage on this electronic part is recommended for running the part safely and stably in a circuit. The electronic part comes with 8 efficient bits which are included within the package. In order to serve the user better, it features WITH DIRECTION CONTROL. As low as -55°C is not a problem for it to operate. An ambient temperature of no more than 125°C should be used. It is strongly recommended that you use at least a voltage of 4.5V when operating this buffer. There is a maximum supply voltage rating of 5.5V. Voltage buffers using COMMON CONTROL control start up automatically.
