Transceiver menggunakan Back-to-Back Tri-State Buffer untuk menghubungkan perangkat yang berbeda ke data berbagi bus komunikasi umum di kedua arah.
Transceiver untuk kontrol dua arah, input atau output, dari perangkat digital atau analog ke bus data bersama. Tidak seperti buffer, Transceiver adalah perangkat dua arah yang memungkinkan data mengalir melalui keduanya.
Dua Buffer IC Tri-State digunakan adalah TTL 74LS125 dan TTL 74LS126.
Buffer tiga keadaan membutuhkan dua input. Input Data (A) dan Kontrol atau Input Aktifkan (EN).
Tri-state Buffer Control, memungkinkan beberapa perangkat untuk berbagi jalur output atau bus dengan memiliki satu perangkat tri-state menggerakkan bus pada waktu sementara, Semua buffer lain tetap dalam keadaan Hi-Z.
