| Order this document by MC14C88B/D MC14C88B Quad Low Power Line Driver The MC14C88B is a low power monolithic quad line driver, using BiMOS technology, which conforms to EIA-232-D, EIA-562, and CCITT V.28. The inputs feature TTL and CMOS compatibility with minimal loading. The outputs feature internally controlled slew rate limiting, eliminating the need for external capacitors. Power off output impedance exceeds 300 W, and current limiting protects the outputs in the event of short circuits. Power supply current is less than 160 mA over the supply voltage range of 4.5 to 15 V. EIA-232-D performance is guaranteed with a minimum supply voltage of 6.5 V. The MC14C88B is pin compatible with the MC1488, SN75188, SN75C188, DS1488, and DS14C88. This device is available in 14 pin plastic DIP, and surface mount packaging.

However, use is extended as the MC14C88 also meets the faster EIA-562 and CCITT V.28 specifications. Slew rate limited outputs conform to the mentioned specifications and eliminate the need for external output capacitors. Low power consumption is made possible by BiMOS technology. Power supply current is limited to less than 160 mA, plus load currents over the supply voltage range of 4.5 V to 15 V (see Figure 2). Outputs The output low or high voltage depends on the state of the inputs, the load current, and the supply voltage (see Table 1 and Figure 3). The graphs apply to each driver regardless of how many other drivers within the package are supplying load current. Table 1. Function Tables Driver 1 Input A H L Output A L H or rise above VEE by more than 39 V, excessive currents will flow at the input pin. Open input pins are equivalent to logic high, but good design practices dictate that inputs should never be left open. Operating Temperature Range The ambient operating temperature range is listed at -40 to +85C and meets EIA-232-D, EIA-562 and CCITT V.28 specifications over this temperature range. The maximum ambient temperature is listed as +85C. However, a lower ambient may be required depending on system use, i.e. specifically how many drivers within a package are used, and at what current levels they are operating. The maximum power which may be dissipated within the package is determined by: P Dmax + TJmax - TA R q JA Drivers 2 through 4 Input *1 H L X Input *2 H X L Output* L H H where: RJA = the package thermal resistance (typically, where: 100C/W for the DIP package, 125C/W for the where: SOIC package); where: TJmax = the maximum operating junction where: temperature (150C); and where: TA = the ambient temperature. PD = { [ (VCC - VOH) IOH ] or [ (VOL - VEE) PD = IOL ] } each driver + (VCC ICC) + (VEE IEE) where: where: where: where: where: where: VCC and VEE are the positive and negative supply voltages; VOH and VOL are measured or estimated from Figure 3; ICC and IEE are the quiescent supply currents measured or estimated from Figure 2. H = High level, L = Low level, X = Don't care. Driver Inputs The driver inputs determine the state of the outputs in accordance with Table 1. The nominal threshold voltage for the inputs is 1.4 Vdc, and for proper operation, the input voltages should be restricted to the range Gnd to VCC. Should the input voltage drop below VEE by more than 0.3 V As indicated, the first term (in brackets) must be calculated and summed for each of the four drivers, while the last terms are common to the entire package. 6 MOTOROLA ANALOG IC DEVICE DATA MC14C88B OUTLINE DIMENSIONS P SUFFIX PLASTIC PACKAGE CASE 646-06 ISSUE L 14 8 B 1 7 NOTES: 1.
