Description : QUAD 2-INPUT MULTIPLEXER WITH STORAGE

QUAD 2-INPUT MULTIPLEXER WITH STORAGE

The SN74LS298 is a QUAD 2-Port Register. It is the logical equivalent of a QUAD 2-INPUT MULTIPLEXER followed by a QUAD 4-bit edge-triggered register. A Common Select input selects between two 4-bit input ports (data sources.) The selected data is transferred to the output register synchronous WITH the HIGH to LOW transition of the Clock input.
The LS298 is fabricated WITH the Schottky barrier process for high speed and is completely compatible WITH all ON Semiconductor TTL families.

• Select From Two Data Sources
• Fully Edge-Triggered Operation
• Typical Power Dissipation of 65 mW
• Input Clamp Diodes Limit High Speed Termination Effects

Description : QUAD 2-INPUT MULTIPLEXER WITH STORAGE

DESCRIPTION
The 74F298 is a high speed QUAD 2-INPUT MULTIPLEXER WITH STORAGE.
It selects 4 bits of data from two sources (ports) under the control of a common Select input (S). The selected data is transferred to the 4-bit output register synchronous WITH the High-to-Low transition of the clock (CP). The 4-bit register is fully edge triggered. The data inputs (I0 and I1) and Select input (S) must be stable only one setup time prior to the High-to-Low transition of the clock for predictable operation.

FEATURES
• Fully synchronous operation
• Select from two data sources
• Buffered, negative edge triggered clock
• Provides the equivalent of function capabilities of two separate
    MSI functions (74F157 and 74F175)
