® M74HCT7259 8BIT ADDRESSABLE LATCH/DECODER/RELAIS DRIVER (OPEN DRAIN,INVERTING OUTPUT) PRELIMINARY DATA LOW POWER DISSIPATION ICC = 4 µA (MAX.) AT TA = 25 °C s COMPATIBLE WITH TTL OUTPUTS VIH = 2V (MIN) VIL = 0.8V (MAX) AT 5V s OUTPUT DRIVE CAPABILITY 90 LSTTL LOADS s HIGH CURRENT OPEN DRAIN OUTPUT UP TO 80 mA The M74HCT7259 is a high speed CMOS 8 BIT ADDRESSABLE LATCH/DECODER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. The M74HCT7259 has single data input (D) 8 LATCH inverted OUTPUTS (Q0-Q7), 3 address inputs (A, B and C), common enable input (ENABLE) and a common CLEAR input.
