Product Overview

The SN74HC253D is a 4-line to 1-line dual Data Selector/Multiplexer with 3-state outputs. It contains inverters and drivers to supply full binary decoding data selection to the AND-OR gates. Separate output-control inputs are provided for each of the two 4-line sections. The 3-state outputs can interface with and drive data lines of bus-organized systems. With all but one of the common outputs disabled (in the high-impedance state), the low impedance of the single enabled output drives the bus line to a high or low logic level. Each output has its own OE\ input. The outputs are disabled when their respective OE\ is high.
  • High-current inverting outputs drive up To 15 LSTTL loads
  • Typical tpd = 9ns
  • Permit multiplexing from n lines to one line
  • Perform parallel-to-serial conversion
  • ±6mA Output drive at 5V
  • 1µA Maximum low input current
  • 80µA Maximum low power consumption
  • 3-state Version of HC153
  • Green product and no Sb/Br
