INTEGRATED CIRCUITS CBTD16210 20-bit level shifting bus switch with 10-bit output enables Product specification Supersedes data of 2000 Sep 25 2000 Oct 12 Philips Semiconductors Product specification 20-bit level shifting bus switch with 10-bit output enables CBTD16210 FEATURES DESCRIPTION • 5Ω switch connection between two ports • TTL compatible control input levels • Designed to be used in 5.5 V to 3.3 V level shifting applications • Package options include shrink small outline (SSOP) and thin The CBTD16210 provides 20 bits of high-speed TTL-compatible bus switching. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. A diode to VCC is integrated in the circuit to allow for level shifting between 5 V inputs and 3.3 V outputs. The device is organized as a dual 10-bit bus switch with separate output-enable (OE) inputs. It can be used as two 10-bit bus switches or as one 20-bit bus switch. When OE is low, the associated 10-bit bus switch is on, and port A is connected to port B. When OE is high, the switch is open, and a high-impedance state exists between the ports. shrink small outline (TSSOP) The CBTD16210 is characterized for operation from –40°C to +85°C.

Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. On-state resistance is determined by the lowest voltage of the two (A or B) terminals. 2000 Oct 12 UNIT 4 µA Ω Philips Semiconductors Product specification 20-bit level shifting bus switch with 10-bit output enables CBTD16210 AC CHARACTERISTICS GND = 0 V; tR; CL = 50 pF LIMITS –40°C to +85°C VCC = 5 V ± 0.5 V PARAMETER DESCRIPTION SYMBOL Min Mean Propagation delay1 tpd UNITS Max 250 ps tPZH Output enable time to HIGH level 1.5 5.0 7.5 ns tPHZ Output disable time from HIGH level 1.0 2.5 4.5 ns tPZL Output enable time to LOW level 1.5 6.0 9.0 ns tPLZ Output disable time from LOW level 1.5 3.5 6.0 ns NOTES: 1.
