74CBTLV16292 LOW-VOLTAGE 12-BIT 1:2 MUX / DEMUX BUS SWITCH INDUSTRIAL TEMPERATURE RANGE LOW-VOLTAGE 12-BIT 1:2 MUX / DEMUX BUS SWITCH WITH INTERNAL PULL DOWN RESISTORS 74CBTLV16292 DESCRIPTION: FEATURES: 5Ω Ω A/B bi-directional switch Isolation Under Power-Off Conditions Make-before-break feature Over-voltage tolerant Ω pull-down resistor to GND Internal 500Ω Latch-up performance exceeds 100mA VCC = 2.3V - 3.6V, normal range ESD >2000V per MIL-STD-883, Method 3015; >200V using machine model (C = 200pF, R = 0) • Available in TSSOP package The CBTLV16292 is a single 12-bit multiplexing / demultiplexing bus switch, which provides high speed switching. This device has very low ON resistance, resulting in under 250ps propagation delay throught the switch. The demultiplexer side has a 500Ω resistor (R pulldown) termination to GND to eliminate floating nodes. When the select (S) input is low, the A port is connected to the B1 port, and the R pulldown is connected to the B2 port. Similarly, when the S input is high, A port is connected to B2 port and the R pulldown is connected to B1 port. • • • • • • • • APPLICATIONS: • 3.3V High Speed Bus Switching and Bus Isolation • Resource sharing FUNCTIONAL BLOCK DIAGRAM 54 2 1A SIMPLIFIED SCHEMATIC, EACH SWITCH 1B1 SW RPULLDOWN RPULLDOWN A 53 SW 12A 27 B 1B2 30 SW 12B1 RPULLDOWN SELECT CONTROL CIRCUITRY RPULLDOWN SW S 30 12B2 1 The IDT logo is a registered trademark of Integrated Device Technology, Inc.

Typical values are at 3.3V, +25°C ambient. 2. The increase in supply current is attributable to each input that is at the specified voltage level rather than VCC or GND. 3. This is measured by the voltage drop between the A and B terminals at the indicated current through the switch.

The propagation delay is the calculated RC time constant of the typical on-state resistance of the switch and the specified load capacitance when driven by an ideal voltage source (zero output impedance). 2. The condition to measure this propagation delay is by observing the change of voltage on the A port introduced by static fields equal to 3V or 0V for 3.3V±0.3V or VCC or 0 for 2.5V±0.2V on B1 and B2 ports to get the required transition. 3. The make-before-break time is the duration between the make and break, during transition from one selected port to another. 4. This parameter is guaranteed by design but not production tested. 3 74CBTLV16292 LOW-VOLTAGE 12-BIT 1:2 MUX / DEMUX BUS SWITCH INDUSTRIAL TEMPERATURE RANGE TEST CIRCUITS AND WAVEFORMS TEST CONDITIONS Symbol VCC(1)= 3.3V±0.3V VCC(2)= 2.5V±0.2V Unit VLOAD 6 2 x Vcc V VIH 3 Vcc V VT 1.5 Vcc / 2 V VLZ 300 150 mV VHZ 300 150 mV CL 50 30 pF SAME PHASE INPUT TRANSITION tPLH tPHL tPLH tPHL OUTPUT VIH VT 0V VOH VT VOL VIH VT 0V OPPOSITE PHASE INPUT TRANSITION Propagation Delay VLOAD VCC 500Ω Pulse(1, 2) Generator VIN CONTROL INPUT GND tPZL VOUT D.U.T.
