DESCRIPTION

· The 74HCT652 is a high-speed CMOS octal bus transceiver and register with 3-state outputs, fabricated using silicon gate C2MOS technology.

· It includes bus transceiver circuits, D-type flip-flops, and control circuitry for multiplexed data transmission from the input bus or internal storage registers.

· Features enable (GAB, GBA) and select (SAB, SBA) control pins for managing transceiver functions and data transfer modes.

· Data can be stored in internal D flip-flops via clock pins (CLOCK AB, CLOCK BA), independent of select or enable control pins.

· All inputs are protected against static discharge and transient excess voltage.

FEATURES

· High-speed operation with fMAX = 55 MHz (typical) at VCC = 4.5V.

· Low power dissipation: ICC = 4µA (max) at TA = 25°C.

· TTL-compatible inputs: VIH = 2V (min), VIL = 0.8V (max).

· Symmetrical output impedance: |IOH| = IOL = 6mA (min).

· Balanced propagation delays: tPLH ≅ tPHL.

· Pin and function compatible with 74 series.

APPLICATIONS

· Suitable for use in bus-oriented systems requiring high-speed data transfer and storage.

· Ideal for applications needing multiplexed data transmission and 3-state output control.

· Can be used in systems where real-time or stored data transfer is required, with flexible control options.
