4 / 10 page Philips Semiconductors Product specification 74F164 8-bit serial-in parallel-out shift register 2000 Dec 18 4 DC ELECTRICAL CHARACTERISTICS (Over recommended operating free-air temperature range unless otherwise noted.) SYMBOL PARAMETER TEST LIMITS UNIT SYMBOL PARAMETER CONDITIONS1 MIN TYP2 MAX VOH High-level output voltage VCC = MIN, VIL = MAX, ±10%V CC 2.5 V VOH High-level out ut voltage CC IL VIH = MIN, IOH = MAX ±5%V CC 2.7 3.4 V VOL Low-level output voltage VCC = MIN, VIL = MAX, ±10%V CC 0.30 0.50 V CC IL VIH = MIN, IOL= MAX ±5%V CC 0.30 0.50 V VIK Input clamp voltage VCC = MIN, II = IIK –0.73 –1.2 V II Input current at maximum input voltage VCC = MAX, VI = 7.0 V 100 µA IIH High-level input current VCC = MAX, VI = 2.7 V 20 µA IILL Low-level input current VCC = MAX, VI = 0.5 V –0.6 mA IOS Short-circuit output current 3 VCC = MAX –60 –150 mA ICC Supply current (total) 4 VCC = MAX 33 55 mA Notes to DC electrical characteristics 1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type. 2. All typical values are at VCC = 5 V, Tamb = 25 °C. 3. Not more than one output should be shorted at a time. For testing IOS, the use of high-speed test apparatus and/or sample-and-hold techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any sequence of parameter test, IOS tests should be performed last. 4. Measure ICC with the serial inputs grounded, the clock input at 2.4 V, and a momentary ground, then applied to Master Reset, and all outputs open.

Here, two devices are combined to form a 16-bit shift register. |
