DESCRIPTION

· The 74ALVCH16821 is a 20-bit bus-interface D-type flip-flop with positive-edge trigger and 3-state outputs.
· It consists of two 10-bit edge-triggered registers, each connected to a 3-state output buffer.
· Each register is independently controlled by clock (nCP) and output enable (nOE) signals.
· Data is transferred to the outputs on a LOW-to-HIGH clock transition.
· Outputs are in high-impedance state when nOE is HIGH.
· Features active bus hold circuitry to maintain valid logic levels on unused inputs.

FEATURES

· Wide supply voltage range: 1.2 V to 3.6 V.
· CMOS low-power consumption.
· Direct interface with TTL levels.
· Current drive: ±24 mA at 3.0 V.
· MULTIBYTE™ flow-through standard pin-out architecture.
· Low inductance multiple VCC and GND pins for noise reduction.
· Output drive capability: 50 Ω transmission lines at 85°C.
· All data inputs have bus hold.
· Complies with JEDEC standards: JESD8-1A, JESD8-5, JESD8B/JESD36.
· ESD protection: HBM exceeds 2000 V, CDM exceeds 1000 V.
· Operating temperature range: -40 °C to +85 °C.

APPLICATIONS

· Suitable for bus interface applications in various electronic systems.
· Ideal for use in systems requiring low-power consumption and wide voltage range.
· Effective in environments with TTL level interfacing needs.
· Useful in applications requiring noise reduction and stable ground connections.
· Applicable in systems needing robust ESD protection and reliable data hold functionality.
