INTEGRATED CIRCUITS 74F382 Arithmetic Logic Unit Product specification IC15 Data Handbook 1990 Jul 12 Philips Semiconductors Product specification Arithmetic logic unit 74F382 FEATURES PIN CONFIGURATION • Performs six arithmetic and logic functions • Selectable Low (clear) and High (preset) functions • Low-input loading minimizes drive requirements • Carry output for ripple expansion • Overflow output for Two’s Complement arithmetic DESCRIPTION The 74F382 performs three arithmetic and three logic operations on two 4-bit words, A and B. Two additional Select (S0–S2) input codes force the Function outputs Low or High. An overflow output is provided for convenience in Two’s Complement arithmetic.

For high-speed expansion using a carry look-ahead generator, refer to the 74F381 data sheet. SF00935 Signals applied to the Select inputs, S0–S2, determine the mode of operation, as indicated in the Function Select Table. An extensive listing of input and output levels is shown in the Function Table. The circuit performs the arithmetic functions for either active-HIgh or active-Low operands, with output levels in the same convention. In the subtract operating modes, it is necessary to force a carry (High for active-HIgh operands, Low for active-Low operands) into the Cn input of the least significant package. Ripple expansion is illustrated in Figure 1. The overflow output OVR is the Exclusive-OR of Cn+3 and Cn+4; a High signal on OVR indicates overflow in Two’s complement operation (See Table 2 for Two’s complement arithmetic). Typical delays for Figure 1 are given in Table 1. When the 74F382 is cascaded to handle word lengths longer than 4 bits, only the most significant overflow (OVR) output is used.

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. 1990 Jul 12 7 Philips Semiconductors Product specification Arithmetic logic unit 74F382 AC ELECTRICAL CHARACTERISTICS LIMITS SYMBOL PARAMETER TEST CONDITION Tamb = +25°C VCC = +5.0V CL = 50pF, RL = 500Ω Tamb = 0°C to +70°C VCC = +5.0V ± 10% CL = 50pF, RL = 500Ω MIN TYP MAX MIN MAX UNIT tPLH tPHL Propagation delay Cn to Fn Waveform 1 3.0 2.5 7.0 4.5 12.0 6.5 2.5 2.5 13.5 7.5 ns tPLH tPHL Propagation delay An or Bn to Fn Waveform 1 3.5 3.0 8.0 6.0 13.5 10.0 3.5 2.5 17.0 11.0 ns tPLH tPHL Propagation delay Si to Fi Waveform 1 5.5 5.5 9.0 7.5 15.0 10.5 5.5 5.5 16.0 12.0 ns tPLH tPHL Propagation delay Ai to Bi to Cn+4 Waveform 1 3.5 3.5 7.0 6.5 10.5 9.5 3.5 3.5 11.5 10.5 ns tPLH tPHL Propagation delay Si to OVR or Cn+4 Waveform 1 7.0 5.0 10.5 8.0 14.5 11.0 6.5 5.0 17.0 12.0 ns tPLH tPHL Propagation delay Cn to Cn+4 Waveform 1 3.0 3.5 4.5 5.0 6.0 6.5 2.5 3.5 6.5 7.0 ns tPLH tPHL Propagation delay Cn to OVR Waveform 1 4.5 3.0 9.0 5.0 13.5 6.5 4.0 3.0 15.0 7.0 ns tPLH tPHL Propagation delay Ai or Bi to OVR Waveform 1 6.0 3.5 9.0 6.5 12.5 9.0 5.5 3.5 16.5 10.0 ns AC WAVEFORMS For all waveforms, VM = 1.5V.
