DESCRIPTION  
TheIDT72V10071/72V11071/72V12071/72V13071/72V14071aredual  
Multimedia FIFOs. The device is functionallyequivalenttotwoindependent  
FIFOs in a single package with all associated control, data, and flag lines  
assignedtoseparatepins.  
Eachofthe twoFIFOs (designatedFIFOAandFIFOB)has a 8-bitinput  
data port (DA0 - DA7, DB0 - DB7) and a 8-bit output data port (QA0 - QA7,  
QB0 - QB7). Each input port is controlled by a free-running clock (WCLKA,  
WCLKB),andaWriteEnablepin(WENA,WENB).Dataiswrittenintoeachof  
thetwoarraysoneveryrisingclockedgeoftheWriteClock(WCLKA,WCLKB)  
whentheappropriateWriteEnablepinisasserted.

2. OEA, OEB VIH, 0.4 VOUT VCC.  
3. Tested with outputs disabled (IOUT = 0).  
4. RCLK and WCLK toggle at 20 MHz and data inputs switch at 10 MHz.  
5. Typical ICC1 = 2[0.17 + 0.48*fS + 0.02*CL*fS] (in mA).  
These equations are valid under the following conditions:  
VCC = 3.3V, TA = 25°C, fS = WCLK frequency = RCLK frequency (in MHz, using TTL levels), data switching at fS/2, CL = capacitive load (in pF).  
6. All Inputs = VCC - 0.2V or GND + 0.2V, except RCLK and WCLK, which toggle at 20 MHz.

NOTE:  
1. When tSKEW1 minimum specification, tFRL maximum = tCLK + tSKEW1  
When tSKEW1 < minimum specification, tFRL maximum = 2tCLK + tSKEW1 or tCLK + tSKEW1  
The Latency Timings apply only at the Empty Boundary (EFA, EFB = LOW).
