Features

  • 8-channel data selection with 3-bit address
  • 3-state output for bus-oriented systems
  • Wide 3-18V supply range
  • 100% tested for 20V quiescent current

Applications

  • Digital multiplexing and data routing
  • Bus-oriented data selection
  • Signal gating and switching

The CD4512BE from Texas Instruments is a CMOS 8-channel data selector/multiplexer in PDIP-16 package. It selects one of eight data inputs via a 3-bit address and presents the selected data at the output. The 3-state output allows direct bus connection. Operates over 3V to 18V and -55C to +125C.

The CD4512BE operates as an 8-channel digital multiplexer. (1) Eight data inputs D0-D7 connect to the internal network. A 3-bit address on A, B, C selects which input connects to output Y. (2) The Output Disable (OD) pin controls the 3-state output. When OD is high, the output enters high-impedance for bus sharing. (3) The Inhibit (INH) pin forces output to logic 0 when high, regardless of address.

Pin Name Function
1-4 D4-D7 Data inputs 4-7
5 INH Inhibit (active high)
6 Y Data output (3-state)
7 OD Output disable
8 VSS Ground
9-11 A-C Address inputs
12-15 D3-D0 Data inputs 3-0
16 VDD Supply (3-18V)
