DESCRIPTION

· 8-bit universal shift/storage registers with multiplexed I/O ports.
· Achieves full 8-bit data handling in a 20-pin package.
· Features function-select (S0, S1) and output-enable (OE1, OE2) inputs for mode selection.
· Supports synchronous parallel loading and 3-state outputs.
· Synchronous clear function with CLR input.
· Operates over military (-55°C to 125°C) and commercial (0°C to 70°C) temperature ranges.

FEATURES

· Multiplexed I/O ports for improved bit density.
· Four modes of operation: Hold, Shift Right, Shift Left, and Load Data.
· Operates with outputs enabled or at high impedance.
· 3-state outputs drive bus lines directly.
· Can be cascaded for n-bit word lengths.
· Package options include Plastic Small-Outline (DW), Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) 300-mil DIPs.

APPLICATIONS

· Stacked or push-down registers.
· Buffer storage.
· Accumulator registers.
