R***A

The seller doesn't take care of you, he (or she) answer you but just give links that you can already get in the product description, then they tell you to find a solution. And sometimes it takes more than a day to answer you. I'm disappointed I can't use the module, he's no use to me!

SN74LS645N Description

***C: 8-BIT TRANSCEIVER, TRUE OUTPUT, PDIP20

***rida Circuit: LOGIC MOT ONLY

***ASI: These octal bus transceivers are designed for asynchronous two-way communication between data buses. The devices transmit data from the A bus to the B bus or from the B bus to the A bus depending upon the level at the direction control (DIR) input. The enable input (G) can be used to disable the device so the buses are effectively isolated.

***OMO Electronic: The -1 versions of the SN74LS640 thru SN74LS642, SN74LS644, and SN74LS645 are identical to the standard versions except that the recommended maximum IOL is increased to 48 milliamperes. There are no -1 versions of the SN54LS640 thru SN54LS642, SN54LS644, and SN54LS645.

***XS: The SN54LS640 thru SN54LS642, SN54LS644, and SN54LS645 are characterized for operation over the full military tempearture range of 55°C to 125°C. The SN74LS640 thru SN74LS642, SN74LS644, and SN74LS645 are characterized for operation from 0°C to 70°C.
