POWER OIC 8-BIT ARESSABE ATC ow r S(on).... Ω Typical Avalanche Energy...75 mj Eight Power MOS Transistor Outputs of 5-mA Continuous Current.5-A Pulsed Current Per Output Output Clamp Voltage at Four istinct Function Modes ow Power Consumption description This power logic 8-bit addressable latch controls open-drain MOS transistor outputs and is designed for general-purpose storage applications in digital systems. Specific uses include working registers, serial-holding registers, and decoders or demultiplexers. This is a multifunctional device capable of storing single-line data in eight addressable latches with -to-8 decoding or demultiplexing mode active-low MOS outputs. Four distinct modes of operation are selectable by controlling the clear (CR) and enable () inputs as enumerated in the function table. In the addressable-latch mode, data at the data-in () terminal is written into the addressed latch. The addressed MOS transistor output inverts the data input with all unaddressed MOS-transistor outputs remaining in their previous states. In the memory mode, all MOS-transistor outputs remain in their previous states and are unaffected by the data or address inputs. To eliminate the possibility of entering erroneous data in the latch, enable should be held high (inactive) while the address lines are changing. In the -to-8 decoding INPUTS CR SIS9A APRI 99 REVISE SEPTEMBER 995 PN V CC S RAIN RAIN RAIN RAIN S N PN W OR N PACKAE (TOP VIEW) or demultiplexing mode, the addressed output is inverted with respect to the input and all other outputs are high. In the clear mode, all outputs are high and unaffected by the address and data inputs. Separate power and logic level ground pins are provided to facilitate maximum system flexibility. Pins,,, and are internally connected, and each pin must be externally connected to the power system ground in order to minimize parasitic inductance. A single-point connection between pin 9, logic ground (N), and pins,,, and, power ground (PN) must be externally made in a manner that reduces crosstalk between the logic and load circuits. The TPIC659 is characterized for operation over the operating case temperature range of C to 5 C. 5 6 7 8 9 OUTPUT OF ARESSE RAIN 9 8 7 6 5 FUNCTION TABE PN CR RAIN7 RAIN6 RAIN5 RAIN S PN EAC OTER RAIN Qio Qio Qio ATC SEECTION TABE SEECT INPUTS RAIN S S S ARESSE 5 6 7 FUNCTION X Qio Memory X Clear Addressable atch 8-ine emultiplexer Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
