The SP526 is fabricated using a T2IN 26 T2OUTB 11 low power BiCMOS process technology, and ENT2 29 T3OUTA 6 incorporates four (4) drivers and four (4) T3 T3IN 28 T3OUTB 10 receivers can be configured via software for ENT3 the selected interface modes at any time. 5 30 T4 T4IN T4OUT The SP526 includes tri-state ability for the 9 ENT4 driver and receiver outputs through separate 43 35 R1INA R1 42 R1OUT enable lines. A shutdown mode is also R1INB 4 ENR1 included through the mode select pins for 41 34 R2INA R2 40 R2OUT power savings. When mated with the SP322 R2INB 3 ENR2 V.11/V.35 Programmable Transceiver, the 39 33 R3INA R3 SP526 provides the four (4) channels needed 38 R3OUT R3INB 2 for handshaking/control lines such as CTS, ENR3 37 32 R4INA RTS, etc. The two transceiver ICs are an R4 36 R4OUT R4INB ideal solution for WAN serial ports in 1 14 ENR4 networking equipment such as routers, D0 13 DSU/CSU s, and other access devices.
