Features

■ Gated (enable/disable) serial inputs ■ Fully buffered clock and serial inputs ■ Asynchronous clear ■ Typical clock frequency 36 MHz ■ Typical power dissipation 185 mW Ordering Code: Connection Diagram Function Table H = HIGH Level (steady state) L = LOW Level (steady state) X = Don't Care (any input, including transitions) ↑ = Transition from LOW-to-HIGH level Q A0, QB0, QH0 = The level of QA, QB, or QH , respectively, before the indicated steady-state input conditions were established. Q An, QGn = The level of QA or QG before the most recent ↑ transition of the clock; indicates a one-bit shift.

3 www.fairchildsemi.com DM74164 Absolute Maximum Ratings(Note 1) Note 1: The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Recommended Operating Conditions Note 2: TA = 25°C and VCC = 5V.

Electrical Characteristics

over recommended operating free air temperature range (unless otherwise noted) Note 3: All typicals are at VCC = 5V, TA = 25°C. Note 4: Not more than one output should be shorted at a time. Note 5: ICC is measured with all outputs OPEN, SERIAL inputs grounded, the CLOCK input at 2.4V, and a momentary ground, then 4.5V, applied to the CLEAR input.
