PINOUT DESCRIPTION PIN SYMBOL DESCRIPTION 1 DIR Directional Control Input 2-9 A1-A8 Bi-directional I/O’s with Tri-State 10 GND Ground 11-18 B8-B1 Bi-directional I/O’s with Tri-State 19 OE Output Enable 20 V CC Supply Power TABLE 2. 54BCT245 ABSOLUTE MAXIMUM RATINGS 1 1. Stresses above the absolute maximum rating may cause permanent damage to the device. Extended operation at the maxi- mum levels may degrade performance and affect reliability. PARAMETER SYMBOL MIN MAX UNIT Supply Voltage Range V CC -0.5 7.0 V Input Voltage Range Control Input 3/I/O Ports2 I/O Ports3 2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. V I -0.5 -0.5 7.0 5.5 V Voltage Range Applied to any Output in the Disable or Power-Off State V O -0.5 7.0 V Voltage Range Applied to any Output in High State V O -0.5 V CC V Current Into Any Output in the Low State I O -- 96 mA Total Power Dissipation @ T A = +55 °C 3 3. Must be able to withstand the additional P D due to short circuit test, e.g. IDS. The PD number is based upon dc values.
