IDT74FCT162H245AT/CT FAST CMOS 16-BIT BIDIRECTIONAL TRANSCEIVER INDUSTRIAL TEMPERATURE RANGE FAST CMOS 16-BIT BIDIRECTIONAL TRANSCEIVER IDT74FCT162H245AT/CT FEATURES: DESCRIPTION: • • • • • The FCT162H245T 16-bit transceiver is built using advanced dual metal CMOS technology. These high-speed, low-power transceivers are ideal for synchronous communication between two busses (A and B). The Direction and Output Enable controls operate these devices as either two independent 8-bit transceivers or one 16-bit transceiver. The direction control pin (xDIR) controls the direction of data flow. The output enable pin (xOE) overrides the direction control and disables both ports. All inputs are designed with hysteresis for improved noise margin. The FCT162H245T has "Bus Hold" which retains the input's last state whenever the input goes to high impedance. This prevents "floating" inputs and eliminates the need for pull-up/down resistors. 0.5 MICRON CMOS Technology High-speed, low-power CMOS replacement for ABT functions Typical tSK(o) (Output Skew) < 250ps Low input and output leakage ≤ 1µA (max.) ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) • Bus Hold retains last active bus state during 3-state • Eliminates the need for external pull up resistors • Available in SSOP and TSSOP packages FUNCTIONAL BLOCK DIAGRAM 1 DIR 2 DIR 1OE 2OE 1A1 2A1 1B1 2B1 1A2 2A2 1B2 2B2 1A3 2A3 1B3 2B3 1A4 2A4 1B4 2B4 1A5 2A5 1B5 2B5 1A6 2A6 1B6 2B6 1A7 2A7 1B7 2B7 1A8 2A8 1B8 2B8 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
