INTEGRATED CIRCUITS 74F640 Octal bus transceiver, inverting (3-State) Product specification IC15 Data Handbook 1989 Nov 27 Philips Semiconductors Product specification Octal bus transceiver, inverting (3-State) FEATURES 74F640 PIN CONFIGURATION • High-impedance NPN base inputs for reduced loading 20 VCC T/R 1 (70µA in High and Low states) • Ideal for applications which require high-output drive and minimal bus loading • Inverting version of 74F245 • Octal bidirectional bus interface • 3-State outputs sink 64mA and source 15mA DESCRIPTION The 74F640 is an octal transceiver featuring inverting 3-State bus compatible outputs in both transmit and receive directions. The B port outputs are capable of sinking 64mA and sourcing 15mA, providing very good capacitive drive characteristics. The device features an Output Enable (OE) input for easy cascading and Transmit/Receiver (T/R) input for direction control. The 3-State outputs, B0–B7, have been designed to prevent output bus loading if the power is removed from the device.

For conditions shown as MIN or MAX, use the appropriate value specified under 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 tests should be performed last. 1989 Nov 27 5 Philips Semiconductors Product specification Octal bus transceiver, inverting (3-State) 74F640 AC ELECTRICAL CHARACTERISTICS LIMITS SYMBOL PARAMETER TEST CONDITION VCC = +5V Tamb = +25°C CL = 50pF, RL = 500Ω VCC = +5V ± 10% Tamb = 0°C to +70°C CL = 50pF, RL = 500Ω MIN TYP MAX MIN MAX UNIT tPLH tPHL Propagation delay An to Bn, Bn to An Waveform NO TAG 2.0 1.0 4.5 2.5 7.0 5.0 2.0 1.0 8.0 5.5 ns tPZH tPZL Output Enable time to High or Low level Waveform 3 Waveform 2 5.5 5.5 6.5 7.0 10.5 10.5 5.0 5.0 12.0 11.0 ns tPHZ tPLZ Output Disable time from High or Low level Waveform 3 Waveform 2 2.0 2.0 3.5 4.5 6.5 7.0 1.5 2.0 8.0 7.5 ns 1989 Nov 27 6 Philips Semiconductors Product specification Octal bus transceiver, inverting (3-State) 74F640 AC WAVEFORMS For all waveforms, VM = 1.5V.
