Two 8-bit back-to-back registers store data flowing in both directions between two bi-directional buses. Data applied to the inputs is entered and stored on the rising edge of the Clock (CPXX) provided that the Clock Enable (CEXX) is Low. The data is then present at the 3-State output buffers, but is only accessible when the Output Enable (OEXX) is Low. Data flow from ‘A’ inputs to ‘B’ outputs is the same as for ‘B’ inputs to ‘A’ outputs. directions between two bidirectional buses • Separate Clock, Clock Enable and 3-State Enable provided for each register • 74F2952 non-inverting • 74F2953 inverting • AM2952/2953 functional equivalent • ‘A’ outputs sink 24mA and source 3mA • ‘B’ outputs sink 64mA and source 15mA • 300 mil wide 24-pin Slim DIP package TYPE TYPICAL fMAX TYPICAL SUPPLY CURRENT (TOTAL) 74F2952 160MHz 105mA 74F2953 160MHz 105mA ORDERING INFORMATION DESCRIPTION 24-pin Plastic Slim DIP (300mil) COMMERCIAL RANGE VCC = 5V ±10%, Tamb = 0°C to +70°C PACKAGE DRAWING NUMBER N74F2952N, N74F2953N SOT222-1 SOL1 N74F2952D, N74F2953D SOT137-1 28-pin Plastic Leaded Chip Carrier N74F2952A, N74F2953A SOT261-2 24-pin Plastic NOTE: 1.

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 Sep 22 7 Philips Semiconductors Product specification Transceivers 74F2952, 74F2953 AC ELECTRICAL CHARACTERISTICS LIMITS SYMBOL TEST CONDITION PARAMETER Tamb = +25°C VCC = +5V CL = 50pF, RL = 500Ω MIN TYP MAX Tamb = 0°C to +70°C VCC = +5V ± 10% CL = 50pF, RL = 500Ω MIN UNIT MAX fMAX Maximum clock frequency Waveform 1 145 160 tPLH tPHL Propagation delay CPBA or CPAB to An or Bn Waveform 1 3.0 3.5 5.0 6.0 7.5 8.5 135 2.5 3.5 8.0 9.0 MHz ns tPZH tPZL Output Enable time OEBA or OEAB to An or Bn Waveform 3 Waveform 4 2.0 3.5 4.5 6.0 7.0 9.5 2.0 3.0 8.0 10.0 ns tPHZ tPLZ Output Disable time OEBA or OEAB to An or Bn Waveform 3 Waveform 4 2.0 1.5 4.0 3.5 8.0 6.5 1.5 1.0 9.0 7.0 ns AC SETUP REQUIREMENTS LIMITS SYMBOL TEST CONDITION PARAMETER Tamb = +25°C VCC = +5V CL = 50pF, RL = 500Ω MIN TYP MAX Tamb = 0°C to +70°C VCC = +5V ± 10% CL = 50pF, RL = 500Ω MIN UNIT MAX ts(H) ts(L) Setup time, High or Low An or Bn to CPAB or CPBA 74F2952 Waveform 2 4.5 3.5 5.0 4.0 ns ts(H) ts(L) Setup time, High or Low An or Bn to CPAB or CPBA 74F2953 Waveform 2 4.0 3.5 4.0 4.0 ns th(H) th(L) Hold time, High or Low An or Bn to CPAB or CPBA Waveform 2 0.0 0.0 0.0 0.0 ns ts(H) ts(L) Setup time, High or Low CEAB, CEBA to CPAB, CPBA Waveform 2 0.0 4.0 0.0 4.0 ns th(H) th(L) Hold time, High or Low CEAB, CEBA to CPAB, CPBA Waveform 2 2.5 2.5 2.5 3.0 ns tw(H) tw(L) CPAB or CPBA pulse width, High or Low Waveform 1 3.0 3.5 3.0 3.5 ns 1989 Sep 22 8 Philips Semiconductors Product specification Transceivers 74F2952, 74F2953 AC WAVEFORMS For all waveforms, VM = 1.5V.
