72 / 267 page ![]() PRELIMINARY PM5366 TEMAP-84 DATASHEET PMC-2010672 ISSUE 1 HIGH DENSITY 84/63 CHANNEL VT/TU MAPPER AND M13 MULTIPLEXER PROPRIETARY AND CONFIDENTIAL 60 Notes on Pin Descriptions: 1. All TEMAP-84 inputs and bi-directionals present minimum capacitive loading and operate at TTL logic levels. 2. All TEMAP-84 outputs and bi-directionals have at least 2 mA drive capability. The bidirectional data bus outputs, D[7:0], have 4 mA drive capability. The outputs TCLK[3:1], TPOS/TDAT[3:1], TNEG/TMFP[3:1], RGAPCLK/RSCLK[3:1], RDATO[3:1], RFPO/RMFPO[3:1], ROVRHD[3:1], TFPO/TMFPO/TGAPCLK[3:1], SBIACT, LAOE/LATPL, RECVCLK1, RECVCLK2 and INTB have 4 mA drive capability. The SBI outputs and telecom bus outputs, SDDATA[7:0], SDDP, SDPL, SDV5, SAJUST_REQ, SAC1FP, LAV5, LAC1J1V1, LADATA[7:0], LADP and LAPL, have 8mA drive capability. The bidirectional SBI signal SDC1FP has 8mA drive capability. 3. Inputs CSB, RSTB, ALE, TMS, TDI and TRSTB have internal pull-up resistors. 4. Input A[12] has an internal pull-down resistor. 5. All unused inputs should be connected to GROUND. 6. Power to the VDD3.3 pins should be applied before power to the VDD1.8 pins is applied. Similarly, power to the VDD1.8 pins should be removed before power to the VDD3.3 pins is removed. |
