FSTU16245 General Description

The Fairchild Switch FSTU16245 provides 16-bits of highspeed CMOS TTL-compatible bus switching. The low On
Resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating
additional ground bounce noise.

The device is organized as a 16-bit switch. There are two 8-bit switches with separate output enable inputs. When
OE is LOW, the switch is ON and Port a is connected to Port B. When OE is HIGH, the switch is OFF and a highimpedance state exists between the A and B Ports. The A and B Ports are protected against undershoot to support an extended range to 2.0V below ground. Fairchild's integrated Undershoot Hardened Circuit (UHC^TM) senses undershoot at the I/O and responds by preventing voltage differentials from developing and turning the switch on. When OE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports.

FSTU162450 General Description

The Fairchild Universal Bus Switch FSTU162450 provides 4-bit, 5-bit, 8-bit, 10-bit, 16-bit, 20-bit of high-speed CMOS TTL-compatible bus switching. The low On Resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.

The FSTU162450 is designed to allow "customer" configuration control of the enable connections. The device can be organized as either a five 4-bit, four 5-bit, two 10-bit or one 20-bit enable bus switch. Also achieveable are 8-bit and 16-bit enabled configurations (see Functional Description).The device's bit configuration is controlled through select pin logic. (see Truth Table). When OE_x is LOW, Port Ax is connected to Port B_x. When OE_x is HIGH, the switch is OPEN.

The A and B Ports are protected against undershoot to support an extended range to 2.0V below ground.Fairchild's integrated Undershoot Hardened Circuit (UHC^TM) senses undershoot at the I/O and responds by preventing voltage differentials from developing and turning the switch on.

FSTU162450 Typical Application

Select pins S₀, S₁, S₂ are intended to be used as static user configurable control pins. The AC performance of these pins has not been characterized or tested. Switching of these select pins during system operation may temporarily
disrupt output logic states and/or enable pin controls.
