INTEGRATED CIRCUITS 74F189A 64-bit TTL bipolar RAM, inverting (3-State) Product specification IC15 Data Handbook 1990 Feb 23 Philips Semiconductors Philips Semiconductors Product specification 64-bit TTL bipolar RAM, inverting (3-State) 74F189A FEATURES * High speed performance * Replaces 74F189 * Address access time: 8ns max vs 28ns for 74F189 * Power dissipation: 4.3mW/bit * Schottky clamp TTL * One chip enable * Inverting outputs (for non-inverting outputs see 74F219A) * 3-State outputs * 74F189A in 150 mil wide SO is preferred options for new designs DESCRIPTION The 74F189A is a high speed, 64-bit RAM organized as a 16-word by 4-bit array. Address inputs are buffered to minimize loading and are fully decoded on chip. The outputs are in high impedance state whenever the chip enable (CE) is high. The outputs are active only in the READ mode (WE = high) and the output data is the complement of the stored data.

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 = 25C. 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 Feb 23 4 Philips Semiconductors Product specification 64-bit TTL bipolar RAM, inverting (3-State) 74F189A AC ELECTRICAL CHARACTERISTICS LIMITS Tamb = +25C SYMBOL PARAMETER TEST CONDITION VCC = +5.0V CL = 50pF, RL = 500 MIN tPLH tPHL tPZH tPZL tPHZ tPLZ tPZH tPZL tPHZ tPLZ Disable time CE to Qn Write recovery time Disable time WE to Qn Enable time WE to Qn Access time Propagation delay An to Qn Enable time CE to Qn Waveform 1 Waveform 2 Waveform 3 Waveform 4 Waveform 4 2.5 2.0 2.0 2.0 2.5 1.5 2.0 2.5 3.5 1.5 TYP 5.0 4.5 3.5 4.0 4.5 3.0 4.0 4.5 5.5 3.5 MAX 8.0 8.0 6.0 7.0 7.0 5.5 6.5 7.5 8.5 6.5 Tamb = 0C to +70C VCC = +5.0V 10% MIN 2.5 2.0 1.5 2.0 2.0 1.5 2.0 2.5 3.0 1.5 MAX 8.0 8.0 7.0 7.5 8.0 6.0 7.0 8.0 9.0 7.0 ns ns ns ns ns UNIT CL = 50pF, RL = 500 AC SETUP REQUIREMENT LIMITS Tamb = +25C SYMBOL PARAMETER TEST CONDITION VCC = +5.0V CL = 50pF, RL = 500 MIN tsu(H) tsu(L) th(H) th(L) tsu(H) tsu(L) th(H) th(L) tsu(L) th(L) tw(L) Setup time, high or low An to WE Hold time, high or low An to WE Setup time, high or low Dn to WE Hold time, high or low Dn to WE Setup time, low CE (falling edge) to WE (falling edge) Hold time, low WE (falling edge) to WE (rising edge) Pulse width, low WE Waveform 4 Waveform 4 Waveform 4 Waveform 4 Waveform 4 Waveform 4 Waveform 4 4.5 4.5 0 0 7.5 6.5 0 0 0 6.5 7.0 TYP MAX Tamb = 0C to +70C VCC = +5.0V 10% MIN 5.0 5.0 0 0 9.0 8.0 0 0 0 7.5 8.0 MAX ns ns ns ns ns ns ns UNIT CL = 50pF, RL = 500 AC WAVEFORMS FOR READ CYCLES An VM tPHL Qn VM tPLH NOTE: For all waveforms, VM = 1.5V.
