7 / 48 page  TLC5970 www.ti.com SBVS140 – MARCH 2010 ELECTRICAL CHARACTERISTICS (continued) At VCC = 10 V to 36 V and TA = –40°C to +85°C. Typical values at VCC = 24 V, FB = 17 V, and TA = +25°C, unless otherwise noted. TLC5970 PARAMETER TEST CONDITIONS MIN TYP MAX UNIT DIFFERENTIAL INTERFACE BLOCK Positive-going input threshold At SDTA-SDTB or SCKA-SCKB pins. Common-mode, VITP 0.2 V voltage VIB = 1.5 V (see Figure 4) Negative-going input threshold At SDTA-SDTB or SCKA-SCKB pins. Common-mode, VITN –0.2 V voltage VIB = 1.5 V (see Figure 4) VITHYS Hysteresis voltage (|VITP – VITN|) Common-mode 30 50 110 mV At SDTA/SDTB/SCKA/SCKB pins. VIH = 12 V II 2 3 mA (other inputs at 0 V), VCC = 24 V At SDTA/SDTB/SCKA/SCKB pins. VIH = 12 V II1 2 3 mA (other inputs at 0 V), VCC = 0 V Input current At SDTA/SDTB/SCKA/SCKB pins. VIH = –7 V II2 –3 –1.2 mA (other inputs at 0 V), VCC = 24 V At SDTA/SDTB/SCKA/SCKB pins. VIH = –7 V II3 –3 –1 mA (other inputs at 0 V), VCC = 0 V At SDTY-SDTZ or SCKY-SCKZ pins. VOD Differential output voltage 1 1.8 3 V 1/2 × RLDIF = 51 Ω (see Figure 6) Change in magnitude of differential At SDTY-SDTZ or SCKY-SCKZ pins. ΔVOD –0.2 0.2 V output voltage(5) 1/2 × RLDIF = 51 Ω (see Figure 6) Steady-state common-mode output At SDTY-SDTZ or SCKY-SCKZ pins. VOC 1.5 VREG/2 3 V voltage 1/2 × RLDIF = 51 Ω (see Figure 6) Change in magnitude of steady-state At SDTY-SDTZ or SCKY-SCKZ pins. ΔVOC –0.2 0.2 V common-mode output voltage(5) 1/2 × RLDIF = 51 Ω (see Figure 6) Internal resistor between differential At SDTA-SDTB or SCKA-SCKB pins. RINT 10 k Ω input pair A pins = 0 V, B pins = 1.8 V At SDTY-SDTZ or SCKY-SCKZ pins. VCC = 0 V, IO Output current with power off –7 V ≤ SDTY/SDTZ/SCKY/SCKZ ≤ 12 V, 1 pin sweep, –10 ±1 20 µA all other outputs are open (5) ΔVOD and ΔVOC are the changes in the steady-state magnitude of VOD and VOC, respectively, that occur when the output data change from a high level to a low level.
