Part Description: 74F257A Quad 2-Input Multiplexer with 3-STATE Outputs

Part Details:

74F257A April 1988 Revised September 2000 Quad 2- 74F257AQuad 2-Input Multiplexer with 3-STATE Outputs Input General Description Features The 74F257A is a quad 2-input multiplexer with 3-STATE s Multiplexer expansion by tying outputs together Mul outputs. Four bits of data from two sources can be selected s Non-inverting 3-STATE outputs using a Common Data Select input. The four outputs s Input clamp diodes limit high-speed termination effects t present the selected data in true (non-inverted) form. The ip outputs may be switched to a high impedance state with a lex HIGH on the common Output Enable (OE) input, allowingthe outputs to interface directly with bus-oriented systems. er w ith 3- Ordering Code: Order Number Package Number Package Description ST 74F257ASC M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow A 74F257ASJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide TE O 74F257APC N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel.
