CBT6800 Datasheet | NXP Semiconductors

FEATURES - 5 Ω switch connection between two ports - TTL patible input and output levels - Outputs are precharged by bias voltage to minimize signal distortion during live insertion DESCRIPTION The CBT6800 provides ten bits of high-speed TTL-patible bus switching. The low on-state resistance of the switch allows bi-directional connections to be made while adding near-zero propagation delay. The device also precharges the B port to a user-selectable bias voltage (BIASV) to minimize live-insertion noise. The CBT6800 is organized as one 10-bit switch with a single enable (ON) input. When ON is low, the switch is on and port A is connected to port B. When ON is high, the switch between port A and port B is open and the B port is precharged to BIASV through the equivalent of a 10 kΩ resistor. The CBT6800 is characterized for operation from - 40°C to 85°C. - Latch-up protection exceeds 100 m A per JESD78 - ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101 QUICK REFERENCE DATA SYMBOL t PLH t PHL CIN COUT ICCZ PARAMETER Propagation delay An to Bn or Bn to An Input capacitance - control pin Output capacitance - I/O pins Total supply current CONDITIONS Tamb = 25°C; GND = 0 V CL = 50 p F; VCC = 5 V VI = 0 V or VCC Outputs disabled; VO = 0 V or VCC Outputs disabled; VCC =5.5 V TYPICAL 250 3.5 8.2 1 UNIT ps p F p F µA ORDERING INFORMATION PACKAGES 24-Pin Plastic TSSOP Type I TEMPERATURE RANGE - 40°C to +85°C ORDER CODE CBT6800 PW DH DWG NUMBER SOT355- 1 PIN CONFIGURATION PIN DESCRIPTION PIN NUMBER 1 13 SYMBOL OE BIASV A1- A10 B1- B10 GND VCC NAME AND FUNCTION Output enable Precharge bias voltage input A-port I/O pins B-port I/O pins - with active pullup Ground (V) Positive supply voltage OE A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 GND 1 2 3 4 5 6 7 8 9 10 11 12 24 23 22 21 20 19 18 17 16 15 14 13 Vcc B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 BIASV 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 23, 22, 21, 20, 19, 18, 17, 16, 15, 14 12 24 SA00505 1999 Oct...
