Bus Operation [MUX]. Set low to select non-multiplexed bus operation. Set high to select multiplexed
bus operation.
Data Bus [D0 to D7] or Address/Data Bus [AD0 to AD7]. In non-multiplexed bus operation (MUX=0),
serves as the data bus. In multiplexed bus operation (MUX=1), serves as an 8-bit multiplexed
address/data bus.
Address Bus [A0 to A5]. In non-multiplexed bus operation (MUX=0), serves as the address bus. In
multiplexed bus operation (MUX=1), these pins are not used and should be tied low.
Bus Type Select [BTS]. Strap high to select Motorola bus timing; strap low to select Intel bus timing.
This pin controls the function of the RD (DS), ALE(AS), and WR (R/ W ) pins. If BTS=1, then these pins
assume the function listed in parentheses ().
Read Input [ RD ] (Data Strobe [DS]).
Framer Selects [FS0 and FS1]. Selects which of the four framers to be accessed.
Chip Selects [ CS ]. Must be low to read or write to any of the four framers.
A6 or Address Latch Enable [ALE] (Address Strobe [AS]). In non-multiplexed bus operation
(MUX=0), serves as the upper address bit. In multiplexed bus operation (MUX=1), serves to demultiplex
the bus on a positive-going edge.
Write Input [ WR ] (Read/Write [R/ W ]).
Positive Supply [VDD]. 5.0 volts ±0.5 volts.
Signal Ground [VSS]. 0.0 volts.
