Description 8-BIT BIDIRECTIONAL BINARY COUNTER (3-STATE)
Datasheet MC74F51 DatasheetMC74F579 Datasheet (PDF)

MC74F579 8-BIT BIDIRECTIONAL BINARY COUNTER (3-STATE) The MC74F579 is a fully synchronous 8-stage up/down counter with multiplexed 3-state I/O ports for bus-oriented applications. It features a preset capability for programmable operation, carry look-ahead for easy cascading and a U/D input to control the direction of counting. All state changes, except for the case of asynchronous reset, are initiated by the rising edge of the clock. TC output is not recommended for use as a clock or asynchrono.

Description OCTAL D-TYPE FLIP-FLOP WITH 3-STATE OUTPUTS
Datasheet MC74F51 DatasheetMC74F574 Datasheet (PDF)

MC74F574 OCTAL D-TYPE FLIP-FLOP WITH 3-STATE OUTPUTS The MC74F574 is a high-speed, low-power octal D-type flip-flop featuring separate D-type inputs for each flip-flop and 3-state outputs for bus oriented applications. A buffered clock (CP) and Output Enable (OE) are common to all flip-flops. This device is functionally identical to the F374 except for the pinouts. • Broadside Pinout Version of F374 • Edge-Triggered D-Type Inputs • Buffered Positive Edge-Triggered Clock • 3-State Outputs for Bus.

Description (MC74F568 / MC74F569) 4-BIT BIDIRECTIONAL COUNTERS(WITH 3-STATE OUTPUTS)
Datasheet MC74F51 DatasheetMC74F569 Datasheet (PDF)

4-BIT BIDIRECTIONAL COUNTERS (WITH 3-STATE OUTPUTS) The MC54/ 74F568 and MC54/74F569 are fully synchronous, reversible counters with 3-state outputs. The F568 is a BCD decade counter; the F569 is a binary counter. They feature preset capability for programmable operation, carry lookahead for easy cascading, and a U/D input to control the direction of counting. For maximum flexibility there are both synchronous and master asynchronous reset inputs as well as both Clocked Carry (CC) and Terminal C.

Description OCTAL REGISTERED TRANSCEIVER / INVERTING / 3-STATE
Datasheet MC74F51 DatasheetMC74F544 Datasheet (PDF)

MC74F544 OCTAL REGISTERED TRANSCEIVER, INVERTING, 3-STATE The MC74F544 Octal Registered Transceivers contain two sets of D-Type latches for temporary storage of data flowing in either direction. Separate Latch Enable (LEAB, LEBA) and Enable (OEAB, OEBA) inputs are provided for each register to permit independent control of inputting and outputting in either direction of data flow. The MC74F544 has an inverting data path. The A outputs are guaranteed to sink 24 mA while the B outputs are rated fo.
