Philips Semiconductors Product specification 74F545Octal bidirectional transceiver (with 3-State inputs/outputs)

21990 Mar 01 853–0375 98992

FEATURES

  • High impedance NPN base inputs for reduced loading (70µA in High and Low states) output
  • 8-bit bidirectional data flow reduces system package count
  • 3-State inputs/outputs for interfacing with bus oriented systems
  • 24mA and 64mA bus drive capability on A and B ports, respectively
  • Transmit/Receive and Output Enable simplify control logic

DESCRIPTION

The 74F545 is an 8-bit, 3-State, high speed transceiver. It provides bidirectional drive for the bus-oriented microprocessor and digital communications systems. Straight through bidirectional transceivers are featured, with 24mA bus drive capability on the A ports and 64mA bus drive capability on the B ports. One input, Transmit/Receive (T/R ) determines the direction of logic signals through the bidirectional transceiver. Transmit enables data from A ports to B ports; Receive enables data from B ports to A ports. The Output Enable input disables both A and B ports by placing them in a 3-State condition. The 74F545 performs the same function as the 74F245, the only difference being package pin assignment. PIN CONFIGURATION 10 11

For conditions shown as MIN or MAX, use the appropriate value under the recommended operating conditions for the applicable type. 2. All typical values are at VCC = 5V, Tamb = 25°C. 3. Not more than one output should be shorted at a time. For testing IOS , the use of high-speed test apparatus and/or sample-and-hold techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any sequence of parameter tests, IOS should be performed last. 4. Measure ICC with outputs open.
