INTEGRATED CIRCUITS 74F1779 8-bit bidirectional binary counter (-State) Product specification IC15 Data Handbook 1989 Apr 06 Philips Semiconductors Philips Semiconductors Product specification 8-bit bidirectional binary counter (3-State) 74F1779 FEATURES • Multiplexed 3-State I/O ports for bus oriented applications • Built-in look-ahead carry capability • Center power pins to reduce effects of package inductance • Count frequency 145MHz typical • Supply current 90mA typical • See 74F269 for 24-pin separate I/O port version • See 74F579 for 20-pin version • See 74F779 for 16-pin version with abbreviated function table DESCRIPTION The 74F1779 is a fully synchronous 8-stage up/down counter with multiplexed 3-State I/O ports for bus-oriented applications. All control functions (hold, count up, count down, synchronous load) are controlled by two mode pins (S0, S1). The device also features carry look-ahead for easy cascading. All state changes are initiated by the rising edge of the clock. When CET is High, the data outputs are held in their current state and TC is held High. the TC output is not recommended for use as a clock or asynchronous reset due to the possibility of decoding spikes. The 74F1779 differs from 74F779 in that it has an additional hold mode as described in the Function Table.

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 = 5V. 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 tests. In any sequence of parameter tests, IOS tests should be performed last.
