Overview

TC74HC299AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC299AP, TC74HC299AF 8-Bit PIPO Shift Register with Asynchronous Clear The TC74HC299A is a high speed CMOS 8-BIT PIPO SHIFT REGISTER fabricated with silicon gate C2MOS technology.

It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.

It has four modes (HOLD, SHIFT LEFT, SHIFT RIGHT and LOAD DATA) controlled by the two selection inputs (S0, S1).

Key Features

  • (Note 1) (Note 2).
  • High speed: fmax = 42 MHz (typ. ) at VCC = 5 V.
  • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C.
  • High noise immunity: VNIH = VNIL = 28% VCC (min).
  • Outputs drive capability : 15 LSTTL loads for QA to QH 10 LSTTL loads for QA’, QH’.
  • Symmetrical output impedance : |IOH| = IOL = 6 mA (min) For QA to QH |IOH| = IOL = 4 mA (min) For QA’, QH’.
  • Balanced propagation delays: tpLH ∼.
  • tpHL.
  • Wide operating voltage.
