The IDT29FCT52A/B/C and IDT29FCT53A/B/C are 8-bit
registered transceivers manufactured using an advanced
dual metal CMOS technology. Two 8-bit back-to-back registers store data flowing in both directions between two bidirectional buses. Separate clock, clock enable and 3-state output
enable signals are provided for each register. Both A outputs
and B outputs are guaranteed to sink 64mA.
The IDT29FCT52A/B/C is a non-inverting option of the
IDT29FCT53A/B/C.

Clock for the A Register. When CEA is LOW, data is entered into the A Register on the LOW-to-HIGH transition
of the CPA signal.
Clock Enable for the A Register. When CEA is LOW, data is entered into the A Register on the LOW-to-HIGH
transition of the CPA signal. When CEA is HIGH, the A Register holds its contents, regardless of CPA signal
transitions.
Output Enable for the A Register. When OEB is LOW, the A Register outputs are enabled onto the B0-7 lines. When
OEB is HIGH, the B0-7 outputs are in the high-impedance state.
Clock for the B Register. When CEB is LOW, data is entered into the B Register on the LOW-to-HIGH transition
of the CPB signal.
Clock Enable for the B Register. When CEB is LOW, data is entered into the B Register on the LOW-to-HIGH
transition of the CPB signal. When CEB is HIGH, the B Register holds its contents, regardless of CPB signal
transitions.
Output Enable for the B Register. When OEA is LOW, the B Register outputs are enabled onto the A0-7 lines. When
OEA is HIGH, the A0-7 outputs are in the high-impedance state.

1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability. No terminal voltage
may exceed +0.5V unless otherwise noted.

1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 5.0V, +25°C ambient and maximum loading.
3. Not more than one output should be shorted at one time. Duration of the short circuit test should not exceed one second.
4. This parameter is guaranteed but not tested.
5. These are maximum IOL values per output, for 8 outputs turned on simultaneously. Total maximum IOL (all outputs) is 512mA for commercial and
384mA for military. Derate IOL for number of outputs exceeding 8 turned on simultaneously.

NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 5.0V, +25°C ambient.
3. Per TTL driven input (VIN = 3.4V); all other inputs at VCC or GND.
4. This parameter is not directly testable, but is derived for use in Total Power Supply calculations.
5. Values for these conditions are examples of the ICC formula. These limits are guaranteed but not tested.
6. IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC + ∆ICC DHNT + ICCD (fCP/2 + fiNi)
ICC = Quiescent Current
∆ICC = Power Supply Current for a TTL High Input (VIN = 3.4V)
DH = Duty Cycle for TTL Inputs High
NT = Number of TTL Inputs at DH
ICCD = Dynamic Current Caused by an Output Transition Pair (HLH or LHL)
fCP = Clock Frequency for Register Devices (Zero for Non-Register Devices)
fi = Input Frequency
Ni = Number of Inputs at fi
All currents are in milliamps and all frequencies are in megahertz.
