Features

■ Complementary outputs ■ Direct overriding (data) inputs ■ Gated clock inputs ■ Parallel-to-serial data conversion ■ Typical frequency 35 MHz ■ Typical power dissipation 105 mW Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the 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 a...h = The level of steady-state input at inputs A through H, respectively. 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 , respectively, before the most recent ↑ transition of the clock.

3 www.fairchildsemi.com DM74LS165 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: C L = 15 pF , RL = 2 kΩ , TA = 25°C and VCC = 5V Note 3: C L = 50 pF , RL = 2 kΩ , TA = 25°C and VCC = 5V Note 4: TA = 25°C and VCC = 5V.

Electrical Characteristics

over recommended operating free air temperature range (unless otherwise noted) Note 5: All typicals are at VCC = 5V, TA = 25° C. Note 6: Not more than one output should be shorted at a time, and the duration should not exceed one second. Note 7: With all outputs OPEN, clock inhibit and shift/load at 4.5V, and a clock pulse applied to the CLOCK input, ICC is measured first with the parallel inputs at 4.5V, then again grounded.
